VI string manipulation

James Barry Donovan — Thu, 17 Jan 2002 16:19:01 GMT

Traditionally my background has been OpenVMS and our company recently purchased a HP UX
solution. We like some information re: the
ability on how to take a name in a flat file and using string maipulation change that name to another, for example...

for every occurrance of BOB found change it to FRANK. We like this to be a script that can be
launched via Crontab.

cat file | sed -e "s/BOB/FRANK/g"

You need to use the sed command to it;

eg. if you have a file called tt.txt then;

cat tt.txt | sed 's/BOB/FRED/g' >

actually you don't even need the cat

sed -e "s/BOB/FRANK/g" file > outfile

As mentioned sed is your answer

sed 's/BOB/FRANK/g' filename > filename2

If you want to create a lot of changes the create a sed script file called sedfile

s/BOB/FRANK/g
S/CRAIG/JOE/g

then call it from the command line

sed -f sedfile filename > filename2

Also if you wanted to do your change while vi'ing the file

:%s/BOB/Frank/g

Make sure you have escaped command mode before entering this.

Same result with awk:

awk '{gsub(/BOB/, FRANK, $0);print}' filename > filename.new
