Bash script to replace all occurrences of a string in all files

Christina has kindly alerted me that Jobbie is a bad word, especially vulgar in Scotland. But the word was littered everywhere in the language files.

So, I wrote a Bash script (blatantly ripped / modified from where credit is due), if anyone’s interested -

Code:

#!/bin/bash
OLDSTRING="Jobbie"
NEWSTRING="Jobster"
DPATH="/home/username/directory/*.txt"
TFILE="/tmp/out.tmp.$$"
for f in $DPATH
do
  if [ -f $f -a -r $f ]; then
    sed "s/$OLDSTRING/$NEWSTRING/g" "$f" > $TFILE && mv $TFILE "$f"
  fi
done
/bin/rm $TFILE

Edit -
rhican’s code:
sed -i "s/orig/new/g" *

Actually that is a shell script, perl would be easier to use:

$ cd /home/username/directory/
$ perl -i -pe 's/Jobbie/Jobster/g' *.txt
