Thanks for replying. I now get it why I had those extra brackets [[ ( lol ). Even though I can see proper contents of the file on echoing the the variable within quotes. But when I pass this variable to another script, in that other script the variable is expanded as the contents of that file plus some extraaaaa file and subfolder names which are stored along with the first script that has passed this variable. I just cant seem to understand why this is happening.
Say my file contains text:
abc
efg
hijklm
And the script file is stored along with other files like a.txt, b.txt and folders fol1, fol2, fol3 etc.
I call this other script p.sh with the argument -x
ie.
Code:
var= "`cat someFile.txt`"
p.sh -x "$var"
But when I see the results poduced by p.sh it contains:
abc
efg a.txt b.txt fol1 fol2
hijklm fol3

catch
catch(n) Tcl Built-In Commands catch(n)
__________________________________________________________________________________________________________________________________________________NAME
catch - Evaluate script and trap exceptional returns
SYNOPSIS
catch script ?varName?
_________________________________________________________________DESCRIPTION
The catch command may be used to prevent errors from aborting command interpretation. Catch calls the Tcl interpreter recursively to exe-
cute script, and always returns without raising an error, regardless of any errors that might occur while executing script.
If script raises an error, catch will return a non-zero integer value corresponding to one of the exceptional return codes (see tcl.h for
the definitions of code values). If the varName argument is given, then the variable it names is set to the error message from interpret-
ing script.
If script does not raise an error, catch will return 0 (TCL_OK) and set the variable to the value returned from script.
Note that catch catches all exceptions, including those generated by break and continue as well as errors. The only errors that are not
caught are syntax errors found when the script is compiled. This is because the catch command only catches errors during runtime. When
the catch statement is compiled, the script is compiled as well and any syntax errors will generate a Tcl error.
EXAMPLES
The catch command may be used in an if to branch based on the success of a script.
if { [catch {open $someFile w} fid] } {
puts stderr "Could not open $someFile for writing
$fid"
exit 1
}
The catch command will not catch compiled syntax errors. The first time proc foo is called, the body will be compiled and a Tcl error will
be generated.
proc foo {} {
catch {expr {1 +- }}
}

catch, error
