portmaster .tcshrc alias

[pacija]

Reading around that portmaster(8) is the way to go, I am trying to do the switch from portupgrade(8). I got used to the command:

sudo portversion -v | grep needs

to check which ports need updating after running portsnap fetch update.

Now, in portmaster(8) I see:

     Print only the ports that have available updates.  This can be used as an
     alias in your shell.  Be sure to fix the line wrapping appropriately.
           portmaster -L |
           egrep -B1 '(ew|ort) version|Aborting|installed|dependencies|
           IGNORE|marked|Reason:|MOVED|deleted|exist|update' | grep -v '^--'

but I do not know how to fix line wrapping and how to properly escape quotes, pipes etc. in my .tcshrc file. I would be grateful if someone who created this alias in tcshrc pasted me the line that works.

This is not directly what you asked for, but I use this:

portsnap fetch update && pkg_version -vIL=

Of course you can put this into an alias. I´m calling it by using history substitution.

I think you meant portsnap and not portmaster. So here is the command.

# portsnap fetch update && pkg_version -IvL=

With pkgng you can use something like the following.

# portsnap fetch update && pkg version -Ivl\<

Generally, it's preferred that posters show what they have tried. In this case, just add an alias line in .cshrc. See tcsh(1) for the format; it is the word alias followed the name and the command, all separated by whitespace. The command should be surrounded by quotes if it contains spaces. In this case:

alias needs "portmaster -L |egrep -B1 '(ew|ort) version|Aborting|installed|dependencies|IGNORE|marked|Reason:|MOVED|deleted|exist|update' | grep -v '^--'"

Thank you wblock@,

sometimes the solution is too easy we oversee it

I tried without the double quotes at first which of course did not work, and then jumped into various combinations of quoting, triple-escaping and similar which even more of course did not work

Now, I will not dare to ask how to break the line...

Line continuation backslashes seem to work. Aliases are a little weird, and there could be special cases. An alias that becomes too long can be converted into a shell script.
