[SOLVED] SlackBuild newbie questions

Konphine · 02-10-2012, 10:55 PM

Hello, I'm trying to create a few *.SlackBuild files with my own additions to the ./configure sections but I'm concerned about what these 2 sections do and if they affect ./configure:

Code:

set -e

and

Code:

find $PKG | xargs file | grep -e "executable" -e "shared object" | grep ELF \
  | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null || true

I'm not 100% sure what either do, and "man set" provided no "-e" option in it's listing so I was unable to find that and Google searches are too wide ranged in various subjects to determine "set -e"'s function.

Thank you in advance.

set -e: This tells bash that it should exit the script if any statement returns a non-true return value.

There's documentation on set here.

The pipeline runs strip --strip-unneeded on each ELF executable in the package. The strip man page has details on what --strip-unneeded does. Most (all?) binary executables in packages are ELFs. The || true ensures that the return code from the pipeline is 0 so, if any of the other commands fail, the set -e does not cause the script to exit.

I see, thank you both for your help. It's very appreciated.
