how to pass command-line parameter to shell script?

Kropotkin · 11-13-2004, 02:15 PM

Hello,

I am new to linux and very new to shell scripting.

How does one pass a command-line parameter to a shell script? In DOS/OS/2 terms, I am looking for the equivalent of %1 etc.

Thanks.

"How does one pass a command-line parameter to a shell script?"

The command line parameters are referenced as $1, $2, etc.

$0 is the name of the command
$1 first parameter
$2 second parameter
$3 third parameter etc. etc
$# total number of parameters
$@ all the parameters will be listed

but in all honesy, you can go to shelldorado.com and get everything you want to know on sh, ksh, csh, bash, javascript etc. Great site with tutorials, examples, everything you will need.

like

Code:

$] ./shell PASS=123 NAME='KKK'

Code:

echo $PASS
ECHO $NAME

Yes, read the messages above which explain how to do this.

That's great -- a 7 year old thread gets a new post and OP Kropotkin replies the same minute!

Sugar, I didn't notice that

xombboxer: I provided you with the solution.
By the way, in the future don't highjack other people's threads (especially 3-year old ones). Create your own thread instead.

)

Given that your shell.sh script looks like you posted above, you can execute it (ans pass the values to the variables) by typing what I suggested. The values will be passed to the script and echo will display the passed values. Is that what you wanted?
