wat grep ik uit met egrep "^ [^ ][^ ]*"

[ap1605]

Wie kan mij uitleggen wat er wordt bedoeld met "^ [^][^]*" in het volgende commando?

lscfg -v|egrep "^ [^][^]*"

Sorry i wrote my question in Dutch.
Who could explain what the meaning this is "^ [^][^]*" in the following command?

lscfg -v|egrep "^ [^][^]*"

The regular expression means:

- a line that begins with a space
- then two literal '^' characters
- followed by zero or more of any character.

Hi,
Jim is not right.
"^ " - line begins with space
"[^][^]" - line contains NOT only ], [, ^
"*" - line contains some letters

I think it is joke.

It isn´t a joke what I want is the Serial- ,FRU-, & partnumber numbers of the resources.

My command is:

lscfg -v| tail +7| egrep "^ [^ ][^ ]*|FRU Number|Serial Number|Part Number"

Thank you for all input

The RE "^ [^][^]*" does match what i said before.

However, I noticed the subject of your post has this for
the RE: "^ [^ ][^ ]*"

That is:
- a line that begins with a space
- excluding lines with any other spaces (consecutively?)
- followed by zero or more of any character

Of course some sample input / output would be helpful.

Actually the first RE does not work. should have tested this first OMIF.

[tt]"^ [^ ][^ ]*|FRU Number|Serial Number|Part Number"[/tt]

matches any line which starts with 2 spaces followed by 1 or more non spaces or contains FRU Number or contains Serial Number or contains Part Number

It seems like you left some spaces out of your first posts. CaKiwi

The regular expression looks to me like:
Either the line contains:
[ul]
[li]FRU Number
[li]Serial Number
[li]Part Number
[li]An anchor to the start of the line, followed by 2 spaces, followed by one non-space, followed by zero or more non-spaces. In other words - an anchor to the start of the line, followed by 2 spaces, followed by one or more non spaces (egrep does not have the equivalent of the '+' metacharacter).
[/ul]
Hope this helps, cheers, Neil
