Groovy execute command with quotes - jenkins

Looking for a way how to run the simple command in groovy (using in jenkins) with quotes inside.
My code is:
"grep 'text ' /tmp/test.txt".execute()
I want to grep all lines with text (and space after it).
But as a result I'm always getting grep of "text" only (without the space). Actually groovy for some reason drops my quotes.


Groovy doesn't handle quotes well. Instead you can use the array form:
['grep', 'text ', '/tmp/test.txt'].execute().text


Try the following:
def res = ['grep', 'text ', 'test.txt'].execute( null, new File( '/tmp/' ) ).text

Cannot replace line after string match in jenkins pipeline using variables

I need to replace a line in a file. If the line starts with the term "url", I need to replace the value.
file.txt --
...
url : http://www.google.com
..
I need to change this value to
url : http://www.facebook.com
I tried the following code but it did not work -
FACEBOOK_URL = "http://www.facebook.com"
sh("sed -i \\"s?^url.*\\$?url: ${FACEBOOK_URL}?\\" file.txt")
I'm using a Jenkins Pipeline. I need to replace the string using a variable.

Jenkins 2 Pipeline builds use Groovy and it is very easy to read the file using readfile and then we can do the changes
def text = readFile "file.txt"
text.replaceAll("url.*", "url: ${FACEBOOK_URL}")
The above code will help in replacing the text in the file, if you want to write the content to file, you can use writeFile

You can use this for replacing a string in a file in Jenkins 2 Pipeline builds:
def text = readFile file: "file.txt"
text = text.replaceAll("%version%", "${VERSION}")
writeFile file: "file.txt", text: text

ImportRange and Concatenate don't work

I like to do this:
=IMPORTRANGE("https://docs.google.com/spreadsheets/d/xxxxxx";=CONCATENAR(F26;"!I23"))
=CONCATENAR(F26;"!I23") is not working on the function.
I was tried some "" and ' ' '
but it doesn't work!. how can i do it?.

I've fix your code as below ant it works in my environment.
=IMPORTRANGE("https://docs.google.com/spreadsheets/d/xxxxxx/edit#gid=0",CONCATENATE(F26,"!I23"))

Reading a file line by line using bash, extracting some data. How?

I want to read a file a extract information from it based on certain tag. For example :
SCRIPT_NAME:mySimpleShell.sh
This is a simple shell. I would like to have this as
Description. I also want to create a txt file our of this.
SCRIPT_NAME:myComplexShell.sh
This is a complex shell. I would like to have this as
Description. I also want to create a txt file our of this.
So when I pass in this file to my shell script, my shell will read it line by line and
when it gets to SCRIPT_NAME, It extract it and save it in $FILE_NAME, then starts writing
the description to a file on disk with $FILE_NAME.txt name. And It does it until It reaches the end of file. If there is 3 SCRIPT_NAME tag, then it creates 3 description file.
Thanks for helping me in advance :)

Read the lines using a while loop. Use a regex to check if a line has SCRIPT_NAME and if so, extract the filename. This is shown below:
#! /bin/bash
while IFS= read -r line
do
if [[ $line =~ SCRIPT_NAME:(.*$) ]]
then
FILENAME="${BASH_REMATCH[1]}"
echo "Writing to $FILENAME.txt"
else
echo "$line" >> "$FILENAME.txt"
fi
done < inputFile

#!/bin/sh
awk '/^SCRIPT_NAME:/ { split( $0, a, ":" ); name=a[2]; next }
name { print > name ".txt" }' ${1?No input file specified}

Help with grep in BBEdit

I'd like to grep the following in BBedit.
Find:
<dc:subject>Knowledge, Mashups, Politics, Reviews, Ratings, Ranking, Statistics</dc:subject>
Replace with:
<dc:subject>Knowledge</dc:subject>
<dc:subject>Mashups</dc:subject>
<dc:subject>Politics</dc:subject>
<dc:subject>Reviews</dc:subject>
<dc:subject>Ratings</dc:subject>
<dc:subject>Ranking</dc:subject>
<dc:subject>Statistics</dc:subject>
OR
Find:
<dc:subject>Social web, Email, Twitter</dc:subject>
Replace with:
<dc:subject>Social web</dc:subject>
<dc:subject>Email</dc:subject>
<dc:subject>Twitter</dc:subject>
Basically, when there's more than one category, I need to find the comma and space, add a linebreak and wrap the open/close around the category.
Any thoughts?

Wow. Lots of complex answers here. How about find:
,
(there's a space after the comma)
and replace with:
</dc:subject>\r<dc:subject>

Find:
(.+?),\s?
Replace:
\1\r
I'm not sure what you meant by “wrap the open/close around the category” but if you mean that you want to wrap it in some sort of tag or link just add it to the replace.
Replace:
\1\r
Would give you
Social web
Email
Twitter
Or get fancier with Replace:
\1\r
Would give you
Social web
Email
Twitter
In that last example you may have a problem with the “Social web” URL having a space in it. I wouldn't recommend that, but I wanted to show you that you could use the \1 backreference more than once.
The Grep reference in the BBEdit Manual is fantastic. Go to Help->User Manual and then Chapter 8. Learning how to use RegEx well will change your life.
UPDATE
Weird, when I first looked at this it didn't show me your full example. Based upon what I see now you should
Find:
(.+?),\s?
Replace:
<dc:subject>\1</dc:subject>\r

I don't use BBEdit, but in Vim you can do this:
%s/(_[^<]+)</dc:subject>/\=substitute(submatch(0), ",[ \t]*", "</dc:subject>\r", "g")/g
It will handle multiple lines and tags that span content with line breaks. It handles lines with multiple too, but won't always get the newline between the close and start tag.
If you post this to the google group vim_use and ask for a Vim solution and the corresponding perl version of it, you would probably get a bunch of suggestions and something that works in BBEdit and then also outside any editor in perl.

You can use sed to do this either, in theory you just need to replace ", " with the closing and opening <dc:subject> and a newline character in between, and output to a new file. But sed doesn't seem to like the html angle brackets...I tried escaping them but still get error messages any time they're included. This is all I had time for so far, so if I get a chance to come back to it I will. Maybe someone else can solve the angle bracket issue:
sed s/, /</dc:subject>\n<dc:subject>/g file.txt > G:\newfile.txt
Ok I think I figured it out. Basically had to put the replacement text containing angle brackets in double quotes and change the separator character sed uses to something other than forward slash, as this is in the replacement text and sed didn't like it. I don't know much about grep but read that grep just matches things whereas sed will replace, so is better for this type of thing:
sed s%", "%"</dc:subject>\n<dc:subject>"%g file.txt > newfile.txt

You can't do this via normal grep. But you can add a "Unix Filter" to BBEdit doing this work for you:
#!/usr/bin/perl -w
while(<>) {
my $line = $_;
$line =~ /<dc:subject>(.+)<\/dc:subject>/;
my $content = $1;
my #arr;
if ($content =~ /,/) {
#arr = split(/,/,$content);
}
my $newline = '';
foreach my $part (#arr) {
$newline .= "\n" if ($newline ne '');
$part =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/;
$newline .= "<dc:subject>$part</dc:subject>";
}
print $newline;
}
How to add this UNIX-Filter to BBEdit you can read at the "Installation"-Part of this URL: http://blog.elitecoderz.net/windows-zeichen-fur-mac-konvertieren-und-umgekehrt-filter-fur-bbeditconverting-windows-characters-to-mac-and-vice-versa-filter-for-bbedit/2009/01/

Ruby script to read output from alias

I have setup an alias in /etc/aliases so that each time an email comes in to a specific address, the text of the email is sent to a Ruby script. Like so:
example: |/etc/smrsh/my_script.rb
I need to know how to read the piped data in my Ruby script..
I have written a simple Perl script that can read the data.. just can't figure out how to do it in Ruby.
Here is the relevant lines in the Perl script:
my $fout = "/tmp/email.out";
open( EM, ">$fout" );
while( <> ) {
chomp;
print EM "$_\n";
}

You can use STDIN to read your pided data. The equivalent of your Perl code would be something like:
out = File.open("/tmp/email.out", "a+")
STDIN.each do |line|
out.puts line
end
