As usual, there are at least 3 different ways to accomplish the task. I would use sed for a one time task. I would probably create a perl program to do it if this was a task that I performed a lot.

I would probably use a combination. Havent had to do anything like this for a long long time.

I would use sed/perl/awk when generating a file.

When modifying an existing file, depending on the complexity of the string comparision look into using ed/vi/perl/awk.

As I do very little work with programs requiring text recognition I would probably use ed or vi and put his in a small script using redirected input

The 'exciting part' part would include <<EOF
g/XXX/s//ZZZ/g
w!
q
EOF

Now, as I am not a regular shell script writer I am expecting someone to improve on this.

string replacement

« on: May 22, 2007, 09:43:05 AM »

hello there !

I just want to know your own way (better ?) to do this :

replace without doing it manually (vi, sed) the string TOTO by TITI in XXX file

my way :
find . -name "XXX" | xargs -t perl -pi.save -e 's/TOTO/TITI/'

or (but with 2 lignes) :
cat XXX | sed 's/TOTO/TITI/g' > XXX.new
cat XXX.new >XXX
in this way i think we keep the permissions...?

thanks !
