This post is all about how I love bash I just re-discovered the power of the command line today while just playing around.

code:

---

cat /var/log/apache/access_log | grep ping.php |  wc -l

---

That was an amazingly easy command to tell how many people accessed ping.php on my webserver. The possibilities are awesome. I also like customized prompts. Oh! the love of bash

I once setup bash scripts run from cron to record a friends radio show to mp3 automatically. His show was thursday from 2:00am to 6:00am so I would miss it very often.

You guys just love all these totally pointless posts dont you? What do you guys think about bash and just command lines in general? I personally think they are very good for so many task that always frustrate me in a GUI.

blah, blah, blah *shutup*

I agree, bash kicks ass. The command line is indispensible in linux.

i like the command line in linux under gnome. i dont like to use straight up command with no window manager. dos is crap because its too limited to use today but bash is incredibly powerfull. it all depends on the shell. i dont like to deal with korn or the c shell. im just too acustomed to bash and lazy to learn something new

Sorry to spoil your mood about bash, but its really the programs you are running that are doing most of the work. Let me break it down for you.

-------------------------------
First you have

cat /var/log/apache/access_log

Which simply reads the contents of a file and writes the contents to the STDOUT.

BASH <<Then with the pipe bash dumps the STDOUT into the STDIN.>>

Which the next command grep uses

grep ping.php

grep in this form takes STDIN and reads from it, matching the lines that have ping.php on it, and writing those lines to STDOUT.

BASH <<Then with the pipe bash dumps the STDOUT into the STDIN.>>

Which the next command wc uses

wc -l

When invoked like this wc will read from STDIN, and count the newlines (enters).
-----------------

So as you can see bash did very little. Also if DOS had cat, grep, and wc that could have been done on a DOS Shell (as ghastly as that sounds).

The power of bash comes from its built-in enviroment variables, language syntax, and of course tab completion (my favorite thing in the world). Im sure you can come up with other reasons, but i won't go over it. I might actually be a fan of C shell or korn shell if i actually used them, but oh well.

I see your point soullace. I was basically just talking about how i love that bash can tie everything in together, and yes i know the DOS prompt supports pipes.

I just love command lines in general, except for the dos one. Command completion is the BEST thing ive ever used in a command line. Anyways, i love bash for more than just pipes.

I like the if then for for in, etc loop syntax and structure, everything just seems to make cense about bash (again the cheesy pun).

soullace, you are too technical for you own good, cant you just let me love bash!?!

And a transparent console is a must for any linux hackx0r, if you are usin x of course...

Sorry to bash on bash. (yes, bad pun intended.)

Command line utilities and the shell are vital to the life of a *nux system. They also make programing and scripting much easier.
