I use awk all the time simply because I have never tried to use sed, a bit like Nigel really

I'm the other way around. I know sed reasonably ell and rarely use awk. awk looks a lot more powerful, but I need to read the man pages again whenever I want to use it.

OK, I'll give you that one
Maybe it's just the people I used to work with that got polarised with one or the other. I used awk a bit, never got around to learning sed.

There are two major differences with awk vs. sed

1) You can use both
2) you can admit to using both

sed seems somewhat simpler for this particular operation.

Try this command :

Code:

echo $PATH | awk -F: '{for (i=1; i<=NF; i++) print $i}'

note that the outer brackets are curly ones, the inner ones are standard brackets, the quotes are standard single quotes.

Hello there,

As a newbie:

The directories in PATH can be hard to distinguish when printed out as
one line with colon .Please, can i have a sample script to display
them,one to a line.

Thank you.
