Scrpit help

[George C. Abraham_2]

Hello Admins

I am writing a script that does a replace within a series of text files. The problem that i am having is with the sed portion of it.

The line that I am replacing will always be line 4. It starts with "startprogram_gui: " followed by other text. I need to replace the other text with "otczsvmsg1"

The problem is that I could use a series of sed commands to do it, but I was hoping that there is a more elegant method.

Any quick ideas?

Good points for all

George -
sed 's/gui.*$/guisomething/' dummy >dummy2

Hi,
try this simple script, using your input file as $1:
#!/usr/bin/sh
while read word rest
do
if [ "$word" = "startprogram_gui:" ]
then
rest="otczsvmsg1"
fi
echo "$word $rest"
done <$1

regards,
John K.

how about just

ex -s -c "4 s/:.*/: otczsvmsg1/|wq" $yourfile

[H.Merijn Brand (procura]

# perl -pi -e 's/gui.*$/guisomething/' file1 file2 file3

will IN PLACE make the substitutions in all files passed

Enjoy, Have FUN! H.Merijn

You can do it quite simple, just like your description of the problem:
sed '4s/^startprogram_gui:.*$/startprogram_gui: otczsvmsg1/'

(On line 4, replace the line if it starts with .... to ...)

Elmer's sed script is so much cleaner!!!
