Script to grep objects' symbol tables

nmgrep.sh

#!/bin/sh

pattern="$1"
shift

if [ $# -gt 1 ]
then
	GREP_OPTIONS="$GREP_OPTIONS --with-filename"
	export GREP_OPTIONS
fi

for file in "$@"
do
	nm -P "$file" | awk '{print $2,$1}' | c++filt | grep --label="$file" --regexp="$pattern"
done

This script requires GNU grep, and an optional C++ demangler, but is otherwise POSIX compatible.

The GNU dependency can be removed by doing something like the following.

nm -P "$file" | awk '{print $2,$1}' | c++filt | grep "$pattern" | while read match
do
	printf '%s:%s\n' "$file" "$match"
done
