What can be used in command line to replace a line starting with "something" in a text file.
Posted on 2006-10-31
I have a text file that looks something like this:
118 => some text …
120 => some text …
121 => some text …
130 => some text …
What I’m trying to do is to replace a line starting with lets say “120” with different text for example “120 => some other text”. Is there an easy way to do this, perhaps with sed, and what would the command look like.
Thanks,
Kate

or to be a little stricter
sed "s/^120 =>.*/120 => some other text/" file >newfile
The ^ means start of line
sed "s/^120 =>.*/120 => some other text/" file >newfile
The ^ means start of line
Is it possible to make the changes within the same file, instead of having to write to a newfile?
Thanks,
