commenting the same line in multiple files

[ogniemi]

I need to comment a line "export SERVER=`hostname`" in .profile files of all users from the list. How to do it fast without editing .profiles manually?


r.m.

 

[mihab]

use sed ; something like this :

sed 's/export SERVER=`hostname`/#export SERVER=`hostname`/' .profile

 

[KenCunningham]

and:

sed 's/export SERVER=`hostname`/#export SERVER=`hostname`/' > temp ; mv temp .profile

to actually make the change. What are you using as your source for .profiles to be changed?

 

[PHV]

Something like this ?
for usr in $(</path/to/list)
do prf=/path/to/home/$usr/.profile
echo '/export SERVER=`hostname`/s/^/#/'"\nwq" | ex - $prf
done

Hope This Helps, PH.
