How would I delete white spaces in a specified file?
Also, I'd like to know what command I would use to take something off a regular expression, and put it onto another.
ie.

.
expression1 <take_off>
.
.
.
expression2 (put here)
.

Any help would be great, thanks! (10 Replies)

...
}
EOF
igawk -f test.awk
