I'm writing windows script host code on login and logout session. When user logs into the system, a timestamp is being recorded and when user logs out again timestamp is being recorded. I have mentioned code below but getting an error as expected identifier and I'm finding it difficult to resolve it.
REM Login Script:
for /f "Tokens=2 Delims=[]" %%i in ('ping -n 1 "%computername%"') do set IP=%%i
echo %username% logged ON %computername%, IP=%IP% # %time% %date% >> F:\$\%username%.txt
REM Logoff Script:
echo %username% logged OFF %computername% # %time% %date% >> F:\$\%username%.txt
REM Startup Script:
for /f "Tokens=2 Delims=[]" %%i in ('ping -n 1 "%computername%"') do set IP=%%i
echo Started up, IP=%IP% # %time% %date% >> F:\$\%computername%.txt
REM Shutdown Script:
echo Shutdown # %time% %date% >> F:\$\%computername%.txt

I am trying to SSH into a machine from a Jenkins Execute shell, check to see if a file exists on the machine and if it does then fail the shell. I have the following code however I can seem to get Jenkins to recognize that the output of echo is "yes" or no"
Please let me know what you think...
sshpass -p ${ServerNodePw} ssh -T -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no ${ServerNodeUser}#${ServerNodeIP} << EOSSH
(ls /Volumes/ServerHD/Users/username/Desktop/JenkinsVMbuild.lock && echo yes) || echo no
2>/dev/null 1>/dev/null
echo "$?"
if [ "$?" = yes ]
then
echo "File found"
exit 1
currentBuild.result = 'FAILURE'
else
echo "File not found"
fi
EOSSH
The value of $? is the exit status of the last executed command (or pipeline). In your case, it would always expand to 0.
You can use command substitution instead if you want to store the echoed string in a variable.
You will also need to properly escape (or quote) the script in your here document. Otherwise $var will be substituted by the caller before passing the script to ssh.
I've just started using docker by copy-pasting pre-made repos from github.
Here is the scenario and steps:
I've passed mysql/shell root password via environment variable -e and these passwords are set as expected inside entry.sh.
I then go inside container and reset shell/mysql root password to something different.
Now the main issue, each time I do docker stop + start from host, it resets passwords to the initial ones of step1.
Please suggest the changes so it retain the modified step2 passwords even I do docker start/stop.
Used entry.sh and dockerfile scripts can be checked from this github repo.
Thanks.
I just noticed that the entry.sh will always update the root password with $MYSQL_RANDOM_ROOT_PASSWORD on docker start. So assuming we already persist the /var/lib/mysql in the host, we can edit the entry.sh a bit to only update the password when /var/lib/mysql doesn't exists:
#!/bin/sh
# start apache
echo "Starting httpd"
httpd
echo "Done httpd"
# check if mysql data directory is nuked
# if so, install the db
echo "Checking /var/lib/mysql folder"
if [ ! -f /var/lib/mysql/ibdata1 ]; then
echo "Installing db"
mariadb-install-db --user=mysql --ldata=/var/lib/mysql > /dev/null
echo "Installed"
# from mysql official docker repo
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
echo >&2 'error: database is uninitialized and password option is not specified '
echo >&2 ' You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_RANDOM_ROOT_PASSWORD'
exit 1
fi
# random password
if [ ! -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
echo "Using random password"
MYSQL_ROOT_PASSWORD="$(pwgen -1 32)"
echo "GENERATED ROOT PASSWORD: $MYSQL_ROOT_PASSWORD"
echo "Done"
fi
tfile=`mktemp`
if [ ! -f "$tfile" ]; then
return 1
fi
cat << EOF > $tfile
USE mysql;
DELETE FROM user;
FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY "$MYSQL_ROOT_PASSWORD" WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'#'localhost' WITH GRANT OPTION;
UPDATE user SET password=PASSWORD("") WHERE user='root' AND host='localhost';
FLUSH PRIVILEGES;
EOF
echo "Querying user"
/usr/bin/mysqld --user=root --bootstrap --verbose=0 < $tfile
rm -f $tfile
echo "Done query"
# setting ssh root password
if [ -z "$SSH_ROOT_PASSWORD" ]; then
echo >&2 'You need to specify SSH_ROOT_PASSWORD'
exit
fi
# Set root password to root, format is 'user:password'.
echo "root:$SSH_ROOT_PASSWORD" | chpasswd
fi;
echo "Generating ssh keys"
if [ ! -f "/etc/ssh/ssh_host_rsa_key" ]; then
# generate fresh rsa key
ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
fi
if [ ! -f "/etc/ssh/ssh_host_dsa_key" ]; then
# generate fresh dsa key
ssh-keygen -f /etc/ssh/ssh_host_dsa_key -N '' -t dsa
fi
#prepare run dir
if [ ! -d "/var/run/sshd" ]; then
mkdir -p /var/run/sshd

ssh-keygen -A

echo "Starting mariadb database"
exec /usr/bin/mysqld --user=root --bind-address=0.0.0.0
Basically we just move this block of code to the if block above it
I would like to create a script for openwrt that every day changes some variables inside the Shadowsocks service. This is the script but i don't know where to put it or how to manage to call it every day or every reboot of router.
#!/bin/sh /etc/rc.common
restart=0
for i in `uci show shadowsocks | grep alias | sed -r 's/.*\[(.*)\].*/\1/'`
do
server=$(uci get shadowsocks.#servers[${i}].alias)
result=$(nslookup $server)
new_ip=$(echo "${result}" | tail -n +3 | awk -F" " '/^Address 1/{ print $3}')
if [ -n "$new_ip" ]; then
logger -t shadowsocks "nslookup $server -> $new_ip"
old_ip=$(uci get shadowsocks.#servers[${i}].server)
if [ "$old_ip" != "$new_ip" ]; then
logger -t shadowsocks "detect $server ip address change ($old_ip -> $new_ip)"
restart=1
uci set shadowsocks.#servers[${i}].server=${new_ip}
fi
else
logger -t shadowsocks "nslookup $server fail"
fi
done
if [ $restart -eq 1 ]; then
logger -t shadowsocks "restart for server ip address change"
uci commit shadowsocks
/etc/init.d/shadowsocks restart
fi
You can use cron utility. Cron is a time-based job scheduler in Unix-like computer OS. It allows to run jobs/programs/scripts at specified times.
OpenWrt comes with a cron system by default, provided by busybox.
Cron is not enabled by default, so your jobs won't be run. To activate cron in Openwrt:
/etc/init.d/cron start
/etc/init.d/cron enable
Ref: https://oldwiki.archive.openwrt.org/doc/howto/cron
Now considering your question, if you want to run mentioned script every day:
Edit cron file using crontab -e command. And write below line.
0 0 * * * sh /path/to/your/script.sh
This command will run your script at 00:00 (every day mid night). You can easily modify the above command to schedule your job at any other time. Good reference to generate cron job entry: https://crontab.guru/
To see if crontab is working properly:
tail -f /var/log/syslog | grep CRON
Now coming to your second question "Run script at every reboot of router":
You can put your script in /etc/rc.local. This file will be executed as as a shell script on every boot up by /etc/rc.d/S95done in Openwrt. So just edit /etc/rc.local with sh /path/to/your/script.sh Make sure your script is executable and doing your task properly.
Sun OS 5.8
Bash shell script
Oracle 10g database
Error 1 the command executing at the time of the error was egrep ORA-\|TNS-\|PLS-\|Error\|PLW-\|IMP-\|EXP-\|RMAN-\|SQL- alert_work.log > alert.err on line 11
The "egrep" line runs successfully when I run it manually. But in a bash script (cron job) it gets the above error. Here is the script:
#!/bin/bash
SID=$ORACLE_SID
DOMAIN=$(uname -n)
DBALIST='dbak#xxx.com'
YESTERDAY=`TZ=CST+24 date +%Y-%m-%d`
cd $ORACLE_HOME/admin/$SID/bdump
mv alert_${SID}.log alert_work.log
touch alert_${SID}.log
cat alert_work.log >> alert_${SID}.hist
egrep ORA-\|TNS-\|PLS-\|Error\|PLW-\|IMP-\|EXP-\|RMAN-\|SQL- alert_work.log > alert.err
if [ `cat alert.err|wc -l` -gt 0 ]
then
mailx -s "${DOMAIN}.${SID} ALERT LOG ERRORS FOUND" $DBALIST < alert.err.log
fi
/usr/bin/mv alert_work.log $ORACLE_HOME/admin/$SID/bdump/hist/alert_${SID}_${YESTERDAY}.log
exit
I am suspicious of your egrep regular expression, The fact that you have not quoted it, and create a script from within a Bash script leads and then run the script, leads me to think that you will end up with:
egrep ORA-|TNS-|PLS-|Error|PLW-|IMP-|EXP-|RMAN-|SQL- alert_work.log > alert.err
which is not what you intended. Try:
egrep 'ORA-\|TNS-\|PLS-\|Error\|PLW-\|IMP-\|EXP-\|RMAN-\|SQL-' alert_work.log > alert.err
That should preserve the back slashes.
I am working with jenkins and I would like to run the maven goals when there is a change in the svn repository. I've attached a picture with my current configuration.
I know that checking the repository every 5 min is crazy. I would like to run it only when there is a new change, but I could not find the way. Anyway, it is not checking the repository. What am I doing wrong?
I believe best practice these days is H/5 * * * *, which means every 5 minutes with a hashing factor to avoid all jobs starting at EXACTLY the same time.
I think your cron is not correct. According to what you described, you may need to change cron schedule to
*/5 * * * *
What you put in your schedule now mean it will poll the SCM at 5 past of every hour.
That's an old question, I know. But, according to me, it is missing proper answer.
The actual / optimal workflow here would be to incorporate SVN's post-commit hook so it triggers Jenkins job after the actual commit is issued only, not in any other case. This way you avoid unneeded polls on your SCM system.
You may find the following links interesting:
Jenkins Wiki's post-commit hook description on Subversion Plugin's doc-site. Here you find documented example of the script you are interested in.

In case of my setup in the corp's SVN server, I utilize the following (censored) script as a post-commit hook on the subversion server side:
#!/bin/sh
# POST-COMMIT HOOK

#TXN_NAME="$3"
LOGFILE=/var/log/xxx/svn/xxx.post-commit.log
MSG=$(svnlook pg --revprop $REPOS svn:log -r$REV)

JENKtest="http://jenkins.xxx.com:8080/view/all/job/xxx/job/xxxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
echo post-commit $* >> $LOGFILE 2>&1
# trigger Jenkins job - xxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx/xxx/Source"
if test 0 -eq $? ; then
echo $(date) - $REPOS - $REV: >> $LOGFILE
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx/xxx/Source" >> $LOGFILE 2>&1
