Hi MadeinGermany,

Thanks for the tips.

The first solution does not work,

Code:
 ./copy_chroot_lib.sh ls echo | sed -n 's#\(/lib\).*#\1#p'
        libselinux.so.1 => /lib
        libc.so.6 => /lib
        libpcre.so.3 => /lib
        libdl.so.2 => /lib
        /lib
        libpthread.so.0 => /lib
        libc.so.6 => /lib
        /lib

While the output from the second solution does not capture only file path, and also captures (0x00...)

Code:
 ./copy_chroot_lib.sh ls echo | sed -n 's#.* => ##p'
/lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f73bfead000)
/lib/x86_64-linux-gnu/libc.so.6 (0x00007f73bfcc3000)
/lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f73bfc4f000)
/lib/x86_64-linux-gnu/libdl.so.2 (0x00007f73bfc49000)
/lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f73bfc28000)
/lib/x86_64-linux-gnu/libc.so.6 (0x00007f2cfa01c000)

I suppose we can exclude the hex value via the following, then capture lines starting with /lib.

Code:
 ./copy_chroot_lib.sh ls echo | sed -E 's#.* => ##;s/[(]0.*//'
        linux-vdso.so.1   <----- should not be included
/lib/x86_64-linux-gnu/libselinux.so.1
/lib/x86_64-linux-gnu/libc.so.6
/lib/x86_64-linux-gnu/libpcre.so.3
/lib/x86_64-linux-gnu/libdl.so.2
        /lib64/ld-linux-x86-64.so.2
/lib/x86_64-linux-gnu/libpthread.so.0
        linux-vdso.so.1
/lib/x86_64-linux-gnu/libc.so.6
        /lib64/ld-linux-x86-64.so.2

Do let me know if you have any better ideas.

Thanks!
