Question

In a mono exe I am creating .sh scripts file containing codes as below

tarcreator.sh:

tar -cvf /data/folder1/folder2/.../xyz.tar /data/...../tarHomeFolder/myTarFolder > /data/logs/tarLogs.txt 

….
and the codes continue.

this .sh file is located in /data/…../tarHomeFolder and in my .exe I call it using “bash ‘full path of .sh file'”

When I run this code in this way, it creates the tar but when I open the tar I see folders from the root directory.. (data/…./tarHomeFolder/myTarFolder/…..) instead of this I want my tar contain only directory structure of its folder (myTarFolder).

Then I changed the code to :

tar -cvf /data/folder1/folder2/.../xyz.tar myTarFolder > /data/logs/tarLogs.txt 

knowing that .sh file is in tarHomeFolder but then my script tells no such file or directory for myTarFolder ..

when I use tar command right in command prompt, using the command

tar -cvf /data/folder1/folder2/.../xyz.tar myTarFolder > /data/logs/tarLogs.txt 

it creates the tar directory structure as I want, so, how can I make it do the same in my bash file created and executed by mono .exe ?

Answer 1

All you need to do is change your directory before running tar. Something like this:

# If your full path to the directory is in DIR = "/data/...../tarHomeFolder/myTarFolder"
cd $(dirname $DIR)
tar -cvf /data/folder1/folder2/.../xyz.tar $(basename $DIR) > /data/logs/tarLogs.txt 

This will leave you with relative paths, starting with myTarFolder, in your tar file.
