Your favorite Linux command/program

[alexander]

What's your favorite Linux command/program(referring to command-line tools)?

 

here are a few i like :)

grep, fork, sex, emerge ... there's many more, so if you happen to guess one, i'll tell you why, and my use for them :)

[rockytriton]

I probably use awk more than anything, but on AIX not linux.

[GAHD]

ls -f

[rockytriton]

oh yea, don't forget this one, I use it all the time too:

 

nohup

[alexander]

lets see some more good ones:

ps -ef f

ls -lsah

du

diff

bg

fg

bc

! - soo cool to use and is extremely useful

[rockytriton]

top - I wish that had that on AIX, it's such a pain to figure out the memory/cpu stats for all of my applications, I have to have the admin give me the info as it is now because I don't have access to the AIX tools that do it ;)

diff

 

The LCS problem, and the solution implemented in diff, are elegant, thought provoking, and imperfect.

[rockytriton]

I have yet to see a perfect diff tool. The one that ships with eclipse is pretty nice though

Moribund and its not in the Linux dist that I know of: biff

 

ps -ef || ps -agux

actually this is an excellent one, so dont make the same mistake i did, of bothering to write your own prime factoring algorithm, it may be fast, but its not smart, referring to factor, its great, fast and excellent, whoever thought of putting it in, should told me, cuz i had to actually write not only a an extremely fast solution with bitmaps and a vector, but a recursive one too, so that first one could have ended in like 2 lines of code...

ok, here's my cool little script for replacing versions of my .jar files in all config files and scripts:

 

#!/bin/sh

SCRIPTS=`find . -name "*.*" -exec grep -l "$1" {} ;`

for file in $SCRIPTS
do
       echo "Editing $file...";
       (cat $file; echo '') | sed 's/'$1'/'$2'/g' > ${file}.tmp;
       sleep 1;
       mv ${file}.tmp $file;
done;

 

oh, and by the way, here's a link to my unix shell scripting tutorial if anyone cares to check it out: http://www.dreamsyssoft.com/unix-shell-scripting/tutorial.php

here's my way of doing it:

dispatch-conf

so, um 8 lines vs 1, i win :naughty:

[rockytriton]

bash: dispatch-conf: command not found

[alexander]

thats because one, you dont have dispatch conf installed, two you dont have a distro with a package management system therefore you can't install dispatch-conf as far as i can remember its a portage util...

 

:) pbttt

[rockytriton]

ok, anyway, I doubt they have a version build for AIX, and anyway, I run it as one line since I wrote it as a shell script, so I still win :)

[alexander]

nope, I do, because i did not have to write a script and it does loads of stuff then blindfully replace stuff in config files, so pbttt I have a more powerful tool that i didnt have to write, and it is one line per execution, and therefore i win.

Actually have a patch for it that makes dispatch-conf a lot more powerful, friend wrote it, allows you to do real cool stuff...

[rockytriton]

ok, ok, I say we just take out the yard stick and get this over with! :)
