Is it my network... or...

[Omaroo]

AULRO is going a bit squiggly this morning for me. It keeps hanging - but is it just me?

[Scouse]

Mine was a little slow about 1/2 hr ago & I even had to refresh the screen once to get it back up again.
It seems OK now.

Damn, I'll have to do some work instead.

[fernockulated]

:roll: mine is a bit slower than usual,only running pathetic dial-up tho,seems slow across the board,not only here,maybe they have some water in the system :roll:

[Farnarkle]

Mine's slow too and I'm on cable - then again what do you expect from BigPoo https://www.aulro.com/afvb/

the place was being spammed to death again after there was some sort of outage in brisbane that affected the link into the joint.

As a Unix systems administrator and development manager - spam is one of my main issues these days. Damn I hate spam - what a waste of so much time and resources.

A unix system admin ..... fantastic

Maybe you can tell me the command to grep for a file across multiple sub directories :?:

Dave https://www.aulro.com/afvb/

[Omaroo]

Dave - have you tried rgrep (recursive grep)? It will search for strings down through a directory structure. If it's not already in your bash path, then you prolly won't have it. Just download the binary for your distro or compile from source....

man:

NAME
rgrep - a recursive, highlighting grep program
SYNOPSIS
rgrep [ options ] pattern [ file ] ...
DESCRIPTION
rgrep, unlike grep(1) and egrep(1) rgrep has the ability to recursively descend directories. The traditional way of performing this kind of search on Unix systems utilizes the find(1) command in conjunction with grep(1). However, this results in very poor performance.
COMMAND LINE OPTIONS

-?

additional help (use '-?' to avoid shell expansion on some systems)

-c

count matches

-h

highlight match (ANSI compatable terminal assumed)

-H

Output match instead of entire line containing match

-i

ignore case

-l

list filename only

-n

print line number of match

-F

follow links

-r

recursively scan through directory tree

-N

Do NOT perform a recursive search

-R 'pat'

like '-r' except that only those files matching 'pat' are checked

-v

print only lines that do NOT match the specified pattern

-x 'ext'

checks only files with extension given by 'ext'.

-D

Print all directories that would be searched. This option is for debugging purposes only. No file is grepped with this option.

-W 'len'

lines are 'len' characters long (not newline terminated).


SUPPORTED REGULAR EXPRESSIONS:

.

match any character except newline



match any digit

e

match ESC char

*

matches zero or more occurences of previous RE

+

matches one or more occurences of previous RE

?

matches zero or one occurence of previous RE

^

matches beginning of line

$

matches end of line

[ ... ]

matches any single character between brackets. For example, [-02468] matches '-' or any even digit. and [-0-9a-z] matches '-' and any digit between 0 and 9 as well as letters a through z.

{ ... }

( ... )

1, 2, ..., 9

matches match specified by nth '( ... )' expression. For example, '([ t][a-zA-Z]+)1[ t]' matches any word repeated consecutively.


EXAMPLES
Look in all files with a 'c' extension in current directory and all its subdirectories looking for matches of 'int ' at the beginning of a line, printing the line containing the match with its line number: (two methods)

rgrep -n -R '*.c' '^int ' .

rgrep -n -x c '^int ' .

Highlight all matches of repeated words in file 'paper.tex':

rgrep -h '[ t]([a-zA-Z]+)[ t]+1[ tn]' paper.tex

rgrep -h '^([a-zA-Z]+)[ t]+1[ tn]' paper.tex

(Note that this version of rgrep requires two passes for this example)

Search through all files EXCEPT .o and .a file below /usr/src/linux looking for the string 'mouse' without regard to case:

rgrep -i -R '*.[^ao]' mouse /usr/src/linux

Search a fixed record length FITS file for the keyword EXTNAME:

rgrep -W80 ^EXTNAME file.fits

(Note that the regular expression '^[A-Z]+' will dump all fits headers.)

Wow - thanks for that. No don't have RGREP

Will check it out.

what the ?????????????????
sorry, is my techno deficiency showing? :oops: :oops: :oops:

[incisor]

with normal grep under bsd it is

grep -d recurse

or

grep -r

[Omaroo]

Yup - the -r switch is pretty useful here too. Rgrep just gives you a lot more options, that's all.

Either way https://www.aulro.com/afvb/

Will that also interrogate compressed files ( ie *.tar.gz files) within those directories or do they have to be decompressed first :?:

Sorry Ferno, but its a already a bit of a techno thread anyway :!:

[Grizzly_Adams]

Recursive grep is one of the nice things to come out of open-source distros. As the other vendors are sticking by the standards (either POSIX or BSD) and there is no recursive grep function in those standards so they never bothered to make one....

Of course even when they do stick to the standards, it's always *their interpretation* of the standards. A good example is MAC addresses. The standard states that each node shall have a seperate MAC address. Sun interpreted a node as being a full machine, whilst everyone else in the world interpreted a node as being a port.

Originally that caused no end of problem when connecting more than 1 LAN port from a Sun server to a switched network, however these days Sun has come to the party (a bit) with a eeprom switch that allows you to set each LAN port to have it's own MAC address. However they still ship with the factory default setting of 1 MAC address for the machine, no matter how many ports :-)

For archives try zgrep with the recursive switch set.

Thanks Inc and Omaroo

Now I have a legit reason for logging on from work.

I can say its a Unix help forum

How much do you know about Oracle :wink:

Dave

[Omaroo]

Oracle? Eek!

I'm a mySQL boy these days, but I was bought up on the PICK database OS.

[fernockulated]

:? this is sounding more and more like it should be in the tech section,




or maybe we should look at creating a new "geek" section for all the 'puta literate people in here https://www.aulro.com/afvb/ https://www.aulro.com/afvb/ https://www.aulro.com/afvb/
