Mac OS X sed, add newline after pattern
Hi,


I've been trying to work out how to add a new line to a file when the pattern matches .dmg.

I've been searching Google but yet not found a working solution.


Help would be appreciated...

Hi.

Add a newline to which file? The DMG file (surely not!) or a file containing a list of files?

Pls. post input and desired output files, show the tools you used/want to use, and explain the logics to be applied.

Sorry,

Not being very clear.

I have a text file that lists dmg's and I want to be able to separate the lines with a newline, with .dmg being the pattern match for the sed command.

So

Code:
1.dmg 2.dmg 3.dmg

to

Code:
1.dmg
2.dmg
3.dmg

Thanks

It's still unclear if the input file contains only .dmg files.

Code:
$ xargs -n1 < file
1.dmg
2.dmg
3.dmg

Try
Code:
tr ' ' '\n' <file.txt

The \n might not work on all tr implementations...

Code:
awk '{gsub(/\.dmg /, "&" RS)}1' file
