Defining variables/arrays in csh from stdn/user input

[eamesj]

hi all,

I'm wanting to use csh (yes, csh) to build an array of variables similar to the argv command below - fyi the (at) is an 'at' symbol but LF wont let me post 'at's in my first post because it thinks it's a URL:

#! /bin/csh -f
foreach i ($argv[-1])
(at) argnum ++
echo '$argv['$argnum'], argument:' $i
end

which gives me variables for $argv[1], $argv[2], etc

But i want these to come from user input so that it does:

Enter list:
texta
textb
textc

or
Enter list:
texta textb textc

gives a set of variables for later use
${variable1}=texta
${variable2}=textb
${variable3}=textc

How can i replace argv with user input?
Thanks

Hi.

If you are using tcsh, you probably can use this.

       $<      Substitutes a line from the standard input, with no further
               interpretation thereafter.  It can be used to read from the
               keyboard in a shell script.  (+) While csh always quotes $<, as
               if it were equivalent to `$<:q', tcsh does not.  Furthermore,
               when tcsh is waiting for a line to be typed the user may type
               an interrupt to interrupt the sequence into which the line is
               to be substituted, but csh does not allow this.

Excerpted from man tcsh, q.v.

In a demo script, I used:

set line = "$<"

In the real csh, I don't know. I think I might have a copy on an old Solaris install, but I have not tried it there.

Best wishes ... cheers, drl

Standard advice: avoid csh family for scripting, use Bourne shell family. For more on this, see: Csh Programming Considered Harmful

I am posting this only on LF, not on LQ.

Thanks drl

OK, looks like csh is a non-starter - Trying to do the same thing but with bash but as im unfamiliar with bash i need a little help.

Againi, I need to ask user for a list, take the replies and perform an action on each of them.

Enter list:
texta
textb
textc

or
Enter list:
texta textb textc

and then i need to know how to run a script on each of them.

foreach $input
anotherscript $text[a-c]
continue

Thanks,
