How do I add executable files from Linux to.gitignore?

Problem

Without giving them an explicit extension or placing them in a dedicated or /bin directory, how do you add linux executable files to.gitignore? Without the “.c” ending, most are named after the C file from which they were compiled.

Solution #1

Is it possible to ignore all but source code files?

For example:

*
!*.c
!Makefile

I’d include them in the project explicitly. gitignore. It’s not really elegant, but I’m guessing you don’t have that many of them in your project.

The actual build process is normally run in a build directory in most developers’ projects. So, all executables,.o,.so,.a, and other files are present, and this build directory has been added to the.gitignore file.

I built a method to add ELF executables to the.gitignore file automatically.

git-ignore-elf:

#!/bin/sh
set -eu
cd "$(git rev-parse --show-toplevel)"
file=.gitignore
new=$file.new.$$
(
if [ -e "$file" ]; then
    cat "$file"
fi
find . -name .git -prune -o -type f ! -name '*.o' ! -name '*.so' \
    -print0 | xargs -0 file | grep ': *ELF ' | sed 's/:.*//' |
sed 's,^./,,'
) | perl -ne 'print if !$already{$_}++' >"$new"
mv "$new" "$file"

This single-script version is here: http://sam.nipl.net/b/git-ignore-elf-1

Here’s a more modular version that relies on other scripts from the same repository (git-root, find-elf, uniqo): http://sam.nipl.net/b/git-ignore-elf

Solution #5

A method of generating differences in your favor. gitignore from all executable files in the current directory in one go:

find . -perm /111 -type f | sed 's#^./##' | sort | diff -u .gitignore -

This creates a diff, ensuring that any manual modifications to the file are preserved. This implies that your.gitignore file has already been sorted. The sed portion just removes the leading./ that find produces.

Because there’s no way to automatically disregard only executable files, you’ll have to manually handle the file.
