Its bash script.. And I thought of SED as the first thing to use for this lol.. Not surprised someone solved that problem with it.. Brilliant tool.

Code:

cat file.txt | awk '{print $1,$2,$3}' > newfile.txt

or

Code:

sed -i 's/:.*/:/' file.txt

JBod if you were using awk surely you would set your separator character to be : via -F and then just print $1

LOL now you guys are arguing about who's method is faster, typical nerds!

Yes indeed

Think it comes down to what you're comfortable with.... I've been known to use
perl -pi.orig -e 's#foo#bar' $file

I vote sed or grok just to be utterly anal

Not heard of sed before but after looking at it seems a very useful and powerful tool. Had to download it via homebrew on osx as the pre-installed version is slightly broken being the POSIX variant rather than the GNU version.

But will give it a shot. Cheers.

Code:

cut -d" " -f 1-3 file1.txt > file2.txt

I normally use awk or sed but there are many ways to skin a cat.
