Hi Everybody

This my first message in this forum
so # echo "Hello world!"

Now about issue that I I have :

I have output of command that give me list of packages that I need to compile :


I need to give this list into input of compile command , but without part inside () also without package version that always goes after '-'.
on other words I should get such line : "virtual/glu virtual/opengl x11-base/xorg-server x11-misc/fireflies"
Here what I done till now ( I will replace echo with compile command after I get to correct version of course )


As I understand problems starts after sed gets to package "x11base/xorg-server-1.7.7-r1" that have '-' not only as version delimeter but also as part of package name.
How can I solve this ?
Also if somebody can suggest totally different way of solving this task I will be glad to see it

You have to keep all the -'s before /. If you want to remove just the last -, you can use

If you want to remove the first - after the last /, you can use

And so on.

Actually I need remove not only '-' but all that goes after '-' too.
So if I have 'x11-base/xorg-server-1.7.7-r1' I should get 'x11-base/xorg-server'

It should be simple enough. Just add .* after the -.

Why not just use bash(1) for such a task:
