Off-line. i.e. script-based? I will be happy to learn a new
tool. FWIW, up to now, I used a simple wrapper for ed:
#!/bin/bash
tmp_script=/tmp/subst.ed.$$
PROGNAME=$(basename $0)
usage () {
echo "
Usage: $PROGNAME [ -h ] regexp substitute files
Does a global search of the (ed-style) regexp and
performs the substitution in place (overwrites!)
for every file listed.
Options:
-h prints this usage message.
" 1>&2
}
while getopts h OPTION
do
case $OPTION in
h) usage
exit 1
;;
\?) echo '$PROGNAME: unknown option $OPTARG'
usage
exit 2
;;
esac
done
shift $(expr $OPTIND - 1)
if [ $# -lt 3 ]; then
echo "$PROGNAME: Wrong number of arguments"
exit 3
fi
regexp=$1
substitute=$2
shift 2
echo "g/$regexp/s//$substitute/g
w
q
" > $tmp_script
for file in "$@"
do
if [ -f $file ]
then echo -n "Making substitution in file $file ... "
orig_version=/tmp/subst.$(basename $file).$$
cp -f $file $orig_version
ed -s $file < $tmp_script
if [ $? -eq 0 ]
then rm -f $orig_version
echo "done"
else mv -f $orig_version $file
echo "error in ed ... aborted"
fi
else echo "File $file does not exist"
fi
done
rm -f $tmp_script
