A small bash script to delete given set of jar files from the WEB-INF/lib of a given warfile.

warclean.sh

#!/bin/bash

main() {
    if [ "$#" -ne 2 ]; then
        EXPLAIN
        exit 0
    fi
    clean "$@"
}

function clean {
    echo cleaning $1
    for i in $(cat $2); do
        zip -d $1 WEB-INF/lib/$i
    done
}

function EXPLAIN {
    cat << EOF1
Usage: $0 <warfile> <list-of-jarfiles>

Cleans the WEB-INF/lib folder of a given war file by deleting all the jar files
mentioned in the file pointed to by the second argument.

EOF1
}

main "$@"

I believe for this bash script you should replace the f.zip arg with $1
( zip -d $1 WEB-INF/lib/$i )

also I pondered building upon it with an optional additive argument for adding additional jars but am unsure the added complexity is worthwhile. anyway it would be something like this:
( something like -> if [ "$#" -eq "3"]; then cat $3 | "s/^//WEB-INF/lib//" | zip -@ -u $1;fi )

added note: you can achieve the same removal of jars in your script without the for-loop by using the stdin option and appending a WEB-INF/lib prefix to each argument such that there is no for loop only the statement below:
cat $2 | sed "s/^//WEB-INF/lib//" | zip -@ -d $1
