Snippet: which-jar.sh

June 22, 2012 · unix gist

I seem to spend a lot of time trying to find files in jars, so I wrote a script a while ago to do this.

#! /bin/sh
set -eu

if [ "$*" = "" ] ; then
        echo "usage: $(basename $0) pattern directory"
        exit 1
fi

P=$1 ;# filename pattern to find
D=$2 ;# directory to search in

for F in $(find $D -type f) ; do
        jar tf $F | grep $P | sed "s/.*/$(echo $F | tr '/' '\\\\/'):\\0/"
done
