Question I need some help with SED and/or GREP...


Basically, I have a text file with a short list of packages (rpms) that I want to install via 'yum', with each package-name separated by a newline:


I want to execute something like:

yum install `command X textfile`

where command is sed and/or grep, and X are the options required to replace each carriage return for a space, so that it effectively results in:

yum install package1 package2 package3 package4

Could somebody please reply with the correct command(s) to achieve the above.

Thanking you in advance.

Kind regards,

something like
yum install `IFS='\n';cat file`
should do the trick ....
W/o sed or grep, though; hope that's not THAT important
to you? :}
