tcsh read command?

johnpaulodonnell · 06-14-2007, 08:30 AM

Hi.

I'm writing a shell script using tcsh - I have no choice in the matter; I'm utilising GMT (Generic Mapping Tools) which only runs from csh/tcsh.

In bash the read command is simple.

I'm having a bit of difficulty with it's counterpart in tcsh...

What I'm tring to do is to assign the number of lines in a file to a variable var

Code:

@ var = (wc -l file | awk '{print $1}' )

the @ is the set equivalent for numerical characters

but tcsh doesn't like this...

so I try the long way around:

Code:

wc -l file | awk '{print $1}' > temp.file
**READ** var < temp.file

- but I don't know the tcsh read syntax. It's something like $< but that's all I can get...

Would appreciate any help

Hya,

I am having great difficulty understanding what you want. Can you describe what you want? Posting error message you get might be also helpful, but only when I know what you want to do.

Hi,

Is this what you want?

Code:

foreach a ("`wc -l *`")
@ b = `echo $a | tr -s ' ' | cut -f 1 -d ' '`
end

or

Code:

foreach a (`wc -l * | tr -s ' ' cut -f 2 -d ' '`)
@ b = a
end
