IS it a blank line?

[cdslaughter]

ok this one has got me going nuts!

I and trying to make a script that looks at a spacific line in a file to se if ther is any text there. but the problem is no mater what I try I get an error.

Any thoughts??

the file "45.txt" has a number of blank lines with no text and when one of these lines are selected is when it error's out.

Her is what I have so far

#! /bin/csh
set blank = ""
set line = $1
set temp = `cat 45.txt | head -$line | tail -1`

if ( $temp == $blank ) then
  echo "It is blank!"
else
  echo "It is not blank"
endif

I get the following error
": Event not found.

have also tried

#! /bin/csh
set blank = ""
set line = $1
set temp = `cat 45.txt | head -$line | tail -1`

if ( $temp == "" ) then     
  echo "It is blank!"
else
  echo "It is not blank"
endif

but with no luck.

overall , there should be specific problem that you want to solve. Why don't you specify what problem you are facing ?

Hi.

Most people avoid csh for scripting, finding that the Bourne shell family does not have the irritating quirks of the csh family.

If you must use csh, then I have found that most error messages involving "events" are related to the use of "!". Remove that from the echo line and try again.

I tried to reproduce your problem with a more modern version of csh called tcsh, and I was not successful, so another alternative might be to try that. Here is a forced example of an event message:

#!/bin/csh

echo Here is !2000

Producing:

% ./s2
2000: Event not found.

Best wishes ... cheers, drl
