Re^2: Changing parameters

Hi,

Thanks for the reply.

Is there another way of changing both the values of i and j without knowing what their current values are?

Your suggestion above does work, but it requires knowing what the current values are of i inorder to change it from 2 to 4.

Thank you.

How about: `perl -pi.bak -e 's!\$i = .*?;!\$i = 4;!' parameter.ph`	[reply] [d/l]

You could just append new values to the file. `echo '$i = 987;' >> parameter.ph` [download] That will override the old values. If you do this often, and do not want the file to grow every time, save the original file and output to a new one. `cp defaults.ph parameter.ph; echo '$i = 987;' >> parameter.ph` [download]	[reply] [d/l] [select]
