I have the directory A/a A/b where both a and b are files.
When I run these commands I get the outputs.
-> tar --include A -v -cf A.tar A
a A
a A/a
a A/b
-> tar --include A/a -v -cf A.tar A
I don`t understand in the 2nd evocation why file A/a is not archived. I believe I do not understand how include works.
I am trying to give tar a list and have it create an archive with the contents. Please help.
Thank you.

I am using security scan software in my Dockerfile and I need to add its bin folder to the path. Its path will contain the version part so I do not know the path until I download the software. My current progress is something like this:
1.Download the software:
RUN curl https://cloud.appscan.com/api/SCX/StaticAnalyzer/SAClientUtil?os=linux --output SAClientUtil.zip
RUN unzip SAClientUtil.zip -d SAClientUtil
2.The desired folder is located: SAClientUtil/SAClientUtil.X.Y.Z/bin/ (xyz mary vary from run to run). Get there using find and cd combination and try to add it to the PATH:
RUN cd "$(dirname "$(find SAClientUtil -type f -name appscan.sh | head -1)")"; \
export PATH="$PATH:$PWD"; # doesn't work
Looks like ENV command is not evaluating the parameter, so
ENV PATH $PATH:"echo $(dirname "$(find SAClientUtil -type f -name appscan.sh | head -1)")"
doesn't work also.
Any ideas on how to dynamically add a folder to the PATH during docker image build?
If you're pretty sure the zip file will contain only a single directory with that exact layout, you can rename it to something fixed.
RUN curl https://cloud.appscan.com/api/SCX/StaticAnalyzer/SAClientUtil?os=linux --output SAClientUtil.zip \
&& unzip SAClientUtil.zip -d tmp \
&& mv tmp/SAClientUtil.* SAClientUtil \
&& rm -rf tmp SAClientUtil.zip
ENV PATH=/SAClientUtil/bin:${PATH}
A simple solution would be to include a small wrapper script in your image, and then use that to run commands from the SAClientUtil directory. For example, if I have the following in saclientwrapper.sh:
#!/bin/sh
cmd=$1
shift
saclientpath=$(ls -d /SAClientUtil/SAClientUtil.*)
echo "got path: $saclientpath"
cd "$saclientpath"
exec "$saclientpath/bin/$cmd" "$#"
Then I can do this:
RUN curl https://cloud.appscan.com/api/SCX/StaticAnalyzer/SAClientUtil?os=linux --output SAClientUtil.zip
RUN unzip SAClientUtil.zip -d SAClientUtil
COPY saclientwrapper.sh /saclientwrapper.sh
RUN sh /saclientwrapper.sh appscan.sh
And this will produce, when building the image:
STEP 6: RUN sh /saclientwrapper.sh appscan.sh
got path: /SAClientUtil/SAClientUtil.8.0.1374

My gunzip structure is like something like this
archive.tgz/manager-34038240834402384/temp1
/temp2/temp4/temp5
/temp3/temp6
I just need the string 'manager-34038240834402384' without extracting whole bundle. How to get it?
I tried tar -tvf which gives me whole path, but I just want above string. How to get it?
tar --list -f archive.tgz | head -n 1
I have an archive named compressed.tar.gz
I want to exract its contents to the folder uncompressed, located in the same directory.
In terminal:
tar -xf compressed.tar.gz -C uncompressed
This works and extracts correctly, however I get an stderror: "Removing leading "/" from member names". I've running above command using -P to suppress the error message as so:
tar -Pxf compressed.tar.gz -C uncompressed
Although the contents are not being extracted at all to uncompressed folder. Any ideas would be greatly appreciated.
Is there a way to append a file into a specific dir inside a tar file?
I have dir1/TarFile.tar. Inside the TarFile.tar there is dir2.
I want to append file.txt (in dir 1) to TarFile.tar under dir2.
Thanks in advance.
As far as i know you can't do this on the fly. You can create directory dir2, move there the file file.txt and update the archive:
cd dir1
mkdir -p dir2
mv file.txt dir2/
tar uvf TarFile.tar dir2/file.txt
The following will extract the files in /root/ directory. But it also creates the parent directories under root. What I need is that the files should be exactly under root folder and not in /root/data/mysql/...
# tar -xvf company_raw_2012-02-22.tgz --directory=/root/
data/mysql/company_raw/data_archive_r_20120222.MYD
data/mysql/company_raw/data_archive_r_20120222.MYI
data/mysql/company_raw/data_archive_r_20120222.frm
If that is not possible, how do I write a program to move these files to the required folder?
I have tried the following and it does work.
--strip-components=3
But I do not know how many folder will be there. So the number 3 may change.
Extract everything to the temp directory with full path and then just walk it moving files to the desired destination?
destdir=/root
tmpdir=/root/tmp
rm -rf $tmpdir
mkdir $tmpdir
tar xf archive.tar.gz -C $tmpdir
find -H $tmpdir -type f -exec mv '{}' $destdir \;
