Top Forums Shell Programming and Scripting Tcsh, using " in a string variable Post 303022347 by DanielDD on Thursday 30th of August 2018 01:07:45 PM

The script works like this:

Code:
mv $file t.tif
if condition1 then
      convert t.tif stuff1 s.tif
      mv s.tif t.tif
endif
 
if condition2 then 
      convert t.tif stuff2 s.tif
      mv s.tif t.tif
endif

if condition3 then 
      convert t.tif stuff3 s.tif
      mv s.tif t.tif
endif

I want to prevent the generation of the temporary files s.tif to optimize the script.


Code:
if condition1 then 
    set s1 = stuff1
else 
    set s1 = ""
endif

# ... same for 2 and 3, and then

convert $file $s1 $s2 $s3 t.tif

The second run should see the two " and form a "string".

It worked, thanks!!!

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list. Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)). FILES
