I do this with a simple function in my .bashrc script:
$> cat >> ~/.bashrc
99 function cscopesetup()
100 {
101 rm cscope.files;
102
103 echo "Populating filenames...";
104 find $SRC/folder1/ -iname "*.c" -print >> cscope.files #folder1
105 find $SRC/folder9/ -iname "*.h" -print >> cscope.files #folder9
106 echo "Driver done"
107 }
ctrl-D
Run this from the bash command:
$> source ~/.bashrc
This will create a file on your home directory with the name cscope.files
If you open this file, you should see the names of all the files you want to tar and backup.
Step 2: Now tar the files
$> tar -cvf myfile.tar -T cscope.files
This will do it. The -T switch takes a file with a list of filenames as an input.
