I'm trying to figure out how to use a shell variable inside my sed command.
I just want to remove a certain part of a path. I've tried three different combinations and none of them work. Here are the three combinations:
and all three of these generate the same error:
sed: -e expression #1, char 8: unknown option to `s'
I just want to remove $test from $file. I'm using tcsh. Does anyone have any ideas on what I can do? Appreciate all the help!

Hi all
I have a script as follows :-
#!/usr/bin/ksh
IDT=`date +"%OH%M%S"`
while true
do
echo ${IDT}
sleep 1
done
I need the time to show me the current runtime value for the time, however this returns the time as at the start of the script.
Any ideas.
Thanks

while
while(n) Tcl Built-In Commands while(n)
__________________________________________________________________________________________________________________________________________________NAME
while - Execute script repeatedly as long as a condition is met
SYNOPSIS
while test body
_________________________________________________________________DESCRIPTION
The while command evaluates test as an expression (in the same way that expr evaluates its argument). The value of the expression must a
proper boolean value; if it is a true value then body is executed by passing it to the Tcl interpreter. Once body has been executed then
test is evaluated again, and the process repeats until eventually test evaluates to a false boolean value. Continue commands may be exe-
cuted inside body to terminate the current iteration of the loop, and break commands may be executed inside body to cause immediate termi-
nation of the while command. The while command always returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the while command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
set x 0
while {$x<10} {
puts "x is $x"
incr x
}
