Shell Programming and Scripting

I know solution to this but I was wondering if its easier than what i think

I have to pass 20 parameters to a script, which of course is not working so I parsed $3 to be a pipe deliminated string

for instance below

a.ksh One Two Compa|Compb|Compc|compd|.............

Now i have to read $3 n parse and store the pipe deliminated value to a individual variable.

My theory was to parse it first and put it in a file and then read individual lines of file into a variable but i was wondering if there was easier way of doing this in one shot

your advice is as always helpful

Thanks

Create an environment file for eg. environ.env which has all your required variables in it

export VAR1="var1"
export VAR2="var2"
export VAR3="var3"
export VAR4="var4"
export VAR5="var5"
export VAR6="var6"
export VAR7="var7"
export VAR8="var8"
export VAR9="var9"
export VAR10="var10"
export VAR11="var11"
export VAR12="var12"
export VAR13="var13"
export VAR14="var14"
export VAR15="var15"
export VAR16="var16"
export VAR17="var17"
export VAR18="var18"
export VAR19="var19"
export VAR20="var20"

Now in your shell script source this environment file

. environ.env


Then you can use the variables anytime in the shell without assigning them again.

but the variables are passed by users and they r not fixed..

I'd also thought of that but..:-(

*oops I meant parameters r passed by user and r not fixed

Why do you say "of course it is not working"? You can have as many parameters as you need, but remember to use {} above $9, e.g...

Code:

$ set a b c d e f g h i j k l m n o p q r s t u v w x y z
$ echo ${20}
t

Thanx so much!!!

It worked..I almost had it working with getopts also

but this is cool I will remember this in future

Thanx so much
