RE: shell script error




I think that by changing the command, you worked around the problem.

the real solution is to look at the syntax of the command "test"  which is
written here as "[" and "]"
[  "whatever you want tested" ] is an alternative way of writing test
"whatever you want tested"
now,  knowing that the brackets are a command,  it is clear that it needs
spaces around the brackets!  ("echosomething" is different from "echo
something")
i didn't see any in your original failing commandline.

BTW the final fgrep solution without test is nicer though

Kind Regards,

Hello,

If my shell programming is as good as I hope, you need the following:

if [ ! -z `/bin/cat /tmp/BACKUP/tmp | /bin/grep 'not accepted'` ] ;
then
echo hi; else echo no; fi

The -z will apply the the output of the entire line, after the grep. I
am sure if I am wrong, someone will be sure and educate us both and
make
us better shell programmers.

Very Respectfully,
Cesar Covarrubias

I hope this is the right list to ask this on.  I am creating a shell

the
command line) gives me an error:

then echo
hi; else echo no; fi

Gives me the following error
-------------
-bash: [: missing `]'
grep: ]: No such file or directory
no

If I run the command like the following, it works just fine:
/bin/cat /tmp/BACKUP/tmp | /bin/grep 'not accepted'

Any help would be appreciated.

Thanks
Steve
