Strip debug symbol from universal static libraries (tested for iOS only)

## Strip debug symbol from universal static libraries

if [ -z "$1" ]
then
	echo "$0 library"
	exit 1
fi

file "$1"|grep 'ar archive random library' >/dev/null 2>&1
if [ $? -ne 0 ]
then
	echo "$1: not a static library"
	exit 1

TMP=`mktemp -d /tmp/tmp.XXXXXX`

for arch in `file "$1"|grep 'architecture '|sed 's/.*(for architecture \(.*\)).*/\1/'`
do
	lipo "$1" -thin $arch -output $TMP/libfoo-$arch-unstripped.a
	strip -S -x -o $TMP/libfoo-$arch.a -r $TMP/libfoo-$arch-unstripped.a
done

rm -f $TMP/*-unstripped.a

lipo -create -output "$1-stripped" $TMP/*.a

rm -f $TMP/*.a
rmdir $TMP

I tried executing this script on my mac but I am getting some strange error when I do the following in the terminal

sh strip-lib.sh ./myLib.a

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can't open input file: /tmp/tmp.Wd6iUM/*.a (No such file or directory)

Can you please let me know if there is anything I need to change in the script or if I am missing something
