I use this here once in a while for such tasks:

# Sami Lempinen * [EMAIL PROTECTED] * http://www.uta.fi/~f1sale

PATH=/bin:/usr/bin:/usr/local/bin
PID=$$

if [ $# -lt 3 ]; then
  echo 1>&2 Usage: $0 old-string new-strings file [files]
  exit 127
fi

OLD=$1; shift;
NEW=$1; shift;

BASENAME=`basename $1`

while [ $# -gt 0 ]; do
  echo Changing $OLD to $NEW in $1...
  sed "s/$OLD/$NEW/g" $1 > /tmp/$BASENAME.$PID
  cp -f /tmp/$BASENAME.$PID $1
  rm -f /tmp/$BASENAME.$PID
  shift
done;

s/blue/red/

Hi,

Is there a way from the console to use a grep like command to search a file
for, say the word "blue" and replace it with "red"? The key is console and
not within Vim, etc. I'm trying to set up a way to automate changing
.Xdefault setups with a simple Bash script.

Thanks,

Jonathan
