Shell Programming and Scripting

Hi,

When i run the below script,

#! /bin/csh
set userid=ficctprd
set kadir=KA_SWCCT_UK_lnswpsm05
setenv pidval `ps -ef | grep keepalive | grep -v keepaliveStub | grep -i $userid | grep -v grep | awk '{ print $2
}'`

I am getting the error "Unmatched ` ".

Could someone please help me to fx this?

Thanks,

In your example the final line is:

Code:

}'`

This should be at the end of the previous line. Should work then.

That's right. One of the differences between C-shells and Bourne-shells is that in Bourne derived shells, if you start quoted text while entering a command (i.e., with a ' or "), a newline does not end the command, but the shell continues the command entry until the quoted text is closed by another ' or ". So, e.g., you can do

Code:

awk 'print { $0 }
       print { $1 }'

I.e., this is one command, but spans mutlitple lines, even without the newline being escaped with a line-terminal backslash, \. But in the csh -- a minor disadvantage I think -- the newline will end a command in this case. So if you want to span a command over several lines in csh, end each line (escept the last) with a backslash (or simply put everything on one line). You're script above seems to betray that you are used to coding in Bourne-derived shells, where you are accustomed to seeing such multiline commands with quotes (or maybe yours was just a typo).
