A difficult SED question...

3saul · 01-09-2006, 08:26 PM

If I have the text
1234x321

and I want to remove anything past the x (ie x321)...where I won't know what is after x...can this be done with SED?

For exampe I may get:

1x1 or 00000000x4511511 - I need to remove whatever is after and including x

You didn´t say which x but I think you meant the second one. Therefore, I put two digits ( .. ) before the x so it would select the second one.

sed 's/\(.*\)x\(.*\)/\1/' file.txt

Thanks for the reply but I'm wanting to be able to separate a resolution string. For example:

I get this string:
800x600

I need to get both 800 and 600 as separate values. In other words delete anything after the x (x600 to get 800) and in another call delete anything before the x (800x to get 600). But this can also apply to other resolutions that are perhaps smaller or larger:

1024x768
90x800

so the SED command has to look for the 'x'

Does it have to be sed? The following returns 600:

Code:

echo 800x600 | cut -dx -f2

That's even better...thanks a lot.
