[SOLVED] Shell script for adding a statement in a file after a particular statement

Aquarius_Girl · 06-28-2010, 01:45 AM

We are building our C++ project in Kdevelop IDE. Every time we run "Run Configure" from the "Build" menu, a file named "libtool" gets automatically generated.

This file contains a statement as "ECHO="echo"".
If we run "Automake", without modifying the "libtool" the system hangs and the computer needs to be restarted.

Therefore every time we run "Run Configure" we need to include the line "echo="echo"" below the statement "ECHO="echo"" manually.

I think a script can be written which does the above on its own.

I am not a shell script programmer, I know the good tutorials for shell scripts are available on the net, but learning scripting only for this task would be time-consuming and painful.

I shall be great-full if someone helps me with this !

I find this a curious line to write as you are saying that as of your 1200+ replies you have never had the need to learn sciprting.
As I said ... just a curious thing to say.

Anyhoo:

Code:

sed -i.bak '/ECHO.*/a"echo="echo""' file

Many thanks to you for writing this. This script must have been a child's play for you.

Can this script be run somehow automatically ? Or every time I need to type this on shell ?

Well I am not familiar with kdevelop but I am sure they must have a section to allow scripting. Otherwise you may have to run manually.

Thanks, I shall look into kdevelop now.
