Sed remove trailing newline
 

Hello everyone. I have a text composed of many lines. Please, can you tell me how can I get rid of the newlines and join the text in one big line? Thank you

Just after I posted I found this
If you have a better (simpler) way I would be thankful if you would post it

slightly laterally

xargs < file

Thank you very much. Your example is (slightly:p) simpler.. But I will decide to use it because it may prove to be.. uh, more portable, yes, that's it :)) Again, thank you. :)

This will remove all newlines:
If you want to find regex matches over whole file with sed, it may be useful to translate newlines to zero-chars '\0'. Then, after filtering, you will be able to translate it back:
PS: bigearsbilly: Really cool! But I encounter an error when `file' contain unmatched single quote (').

I never said it was perfect!

Ok so it's a rubbish solution except for simple examples
;)

I seem to recall using

See if that works.

For every sed one liner, there is a perl one:

Why to have the cat ?

Isnt that UUOC

You can do the same without `cat' if you want:

What is UUOC?

I have no idea but, Unnecessary Use Of Cat would match :P

that's

:)

While I agree you can do that w/o cat this example really is a minor nit IMHO. A better example of UUOC would be those situations where you "cat file|awk" or "cat file|sed" where you can "awk file" or "sed -i file".

UUOC indeed, but i would say the first example
is easier to scan and edit:

cat file | sort -k1,2rn | cut -d\ -f3-9 | grep -v INFO

sort -k1,2rn < file | cut -d\ -f3-9 | grep -v INFO

Looks like you've got a solution already, but I thought I'd mention the fmt command, which is aimed at text formatting - unfortunately (at least on HP-UX!) it doesn't have an option to fill/join lines to an arbitrary width. But it's occasionally useful to fill lines to a certain width... in particular, in vi typing !}fmt will line-fill the current paragraph, which is very handy when entering a lot of text.

"xargs < file" is the nicest one-liner I've seen in a long time :-)
