There's an 'urgent' forum here if it truly is, but this is not it. I am here though, so:

to comment:

sed -i 's@^/opt/admin/fastpg/bin/fastpg.exe -c -=NET@#/opt/admin/fastpg/bin/fastpg.exe -c -=NET@g' scriptfilename

to uncomment:

sed -i 's@^#/opt/admin/fastpg/bin/fastpg.exe -c -=NET@/opt/admin/fastpg/bin/fastpg.exe -c -=NET@g' scriptfilename

Or you could make two copies of the script file, modify one of them, and make the original a symlink that can be easily changed to point to whichever one you want.
