Hello.
I've written up a script, that populates a variable with a list of tapes returned from my library. For example:
701940L3,701941L3,701942L3,701943L3,701944L3,701945L3,701946L3,701947L3,701948L3
So now, the variable "TAPELIST" contains those numbers, delimited by commas. I'd like to... (6 Replies)
Hi all,
I couldn't find an answer for this easy question, probably because the keywords I used in the search are too generic.

NumFiles=$(ls | wc -l)
for i in {1..$NumFiles}; do
Say $NumFiles = 5. Bash... (3 Replies)

eval
eval(1T) Tcl Built-In Commands eval(1T)__________________________________________________________________________________________________________________________________________________NAME
eval - Evaluate a Tcl script
SYNOPSIS
eval arg ?arg ...?
_________________________________________________________________DESCRIPTION
Eval takes one or more arguments, which together comprise a Tcl script containing one or more commands. Eval concatenates all its argu-
ments in the same fashion as the concat command, passes the concatenated string to the Tcl interpreter recursively, and returns the result
of that evaluation (or any error generated by it). Note that the list command quotes sequences of words in such a way that they are not
further expanded by the eval command.
EXAMPLE
This procedure acts in a way that is analogous to the lappend command, except it inserts the argument values at the start of the list in
the variable:
proc lprepend {varName args} {
upvar 1 $varName var
# Ensure that the variable exists and contains a list
lappend var
# Now we insert all the arguments in one go
set var [eval [list linsert $var 0] $args]
}
