<div dir="auto">I strongly suggest the loop. In general use, the length of some of the variables could be too large even for tcsh.

<p>The sed works fine and is not a problem. The only problem with
the script is with: alias update_makefiles 'string'<br>
</p>
<p>It's just that the string part is too long for csh [

<p>Which is why if you shorten the string, for example split it into
two alias (like update_makefiles01 and update_makefiles02), then
the script works fine:<br>

<div>If I understand correctly, sed is the main problem.
So, isn’t there an alternative to sed? (e.g. awk, perl,
