[SOLVED] Replace Data in a file using Perl or any other utility

mfarch99 · 08-13-2013, 10:34 AM

I have a file with text that I need to find and replace. The text is not always the same but it does have a consistent method for searching. For instance the text would be machine: NNN where NNN would change. I want to replace machine: NNN with machine: myname.
How do i perform a search and replace for inconsistent data and replace it with consistent data.

With perl I would use perl -p -i -e 's/machine:./machine:myname /g' ALLJOBS.08.txt

The problem with this is it doesn't replace the original machine names just appends the new name to the original name.

sed:

Code:

sed s/"machine: ..."/"machine: myname"/g mfarch99.txt

Code:

sed -E 's/machine\:\ [0-9]+/machine\:\ myname/g' ALLJOBS.08.txt

Should do the trick:

Code:

cat test
machine: 2323123
machine: 1232929292

Code:

sed -E 's/machine\:\ [0-9]+/machine\:\ myname/g' test
machine: myname
machine: myname
