Help! I sux @ Unix

[Nitrofox125]

Well actually I have a few different questions here.

1. How do I use wildcards in a delete? I have lines like this say:
VALUES('-1','2','Whee','OMG');
And I want them to end up like this:
VALUES('2','Whee','OMG');
With the -1 gone. However I can't just do a normal find and replace, because the -1 changes with every line. what program can do this and what is the command/way to do this?
The closest i got was in VI
:s/VALUES('*',/VALUES(/g but that didn't work.

2. How to list only directories in unix ls?
What I'm looking for is the unix equivilent to
dir /s /ad /s *

Thanks

study up on your regular expressions.

and, for god's sake, read the man or info pages.

i don't know much about vi. maybe try

Code: Select all

:s/VALUES('[*]',/VALUES(/g

and, i always use

Code: Select all

ls -lap

(aliased to l) to list directories.

I looked at the man pages for ls and it didn't really give me what I wanted... :
Thanks for that other info though...

I was thinkin maybe like :s/VALUES('[0-9]',/...... or something might work..

2. How to list only directories in unix ls?

'ls' does not support listing only directories.

To show all directories try the following:
find -type d -maxdepth 1

If you are new to *nix, or anything for that matter, www.google.com is your friend.

sed I think might be capable of doing what you want. You'll have to read up on the syntax though as I don't know it off the top of my head.

http://unix.about.com/library/glossary/ ... tution.htm

It also has the valid wildcard characters defined for *nix.

This finds all directories below this one:

find . -type d

If you want to make this command available in a short form (for example, if you want to be able to call "lsdir" and get this result) put the following line in a file called .bashrc in your home (~) directory.

alias lsdir='find . -type d'

[Instig8]

If you don't want subs, maybe use:

alias lsdir='ls -lp |grep /'

Now, when you type lsdir you only see directories. A million ways to skin a cat.

Lol... find . -type d -maxdepth 1 worked quite well. Thanks all!
