You are right - it's the combination of spaces and wildcards in one pattern that is the killer. Spaces only you could deal with by enclosing in double quotes, which in turn prevent the expansion of the wildcards. Catch 22.
Solution would be escaping every single space with a \ , and using the (deprecated, as generally dangerous) eval command:
Please make sure you know EXACTLY what is being evaled, as it would rigorously evaluate and execute e.g. rm / ...
And, enclose "$FN" in double quotes in my above script as well...
I'm trying to figure out how to build a small shell script that will find old .shtml files in every /tgp/ directory on the server and delete them if they are older than 10 days...

Hi,
I have a directory with possibly around 800,000 files in it.
What is the fastest way to list file(s) in this directory with a wildcard.
for example would
ls -1 *.abcdefg.Z
or
find . -name "*.abcdefg.Z"
be the fastest way to find all of the files that end with .abcdefg.Z... (6 Replies)

I have a number of files in a directory that can be grouped with something like "ls | grep SH2". I would like to move each file in this list to another directory.

Greetings. I know enough Unix to be dangerous (!) and know that there is a clever way to do the following and it will save me about a day of agony (this time) and I will use it forever after! (many days of agony saved in the future)!

I think I must be missing something obvious but I have a file containing a list of files and paths, some with wildcard, others with spaces. e.g.

eval
eval(n) Tcl Built-In Commands eval(n)
__________________________________________________________________________________________________________________________________________________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.
EXAMPLES
Often, it is useful to store a fragment of a script in a variable and execute it later on with extra values appended. This technique is
used in a number of places throughout the Tcl core (e.g. in fcopy, lsort and trace command callbacks). This example shows how to do this
using core Tcl commands:
set script {
puts "logging now"
lappend $myCurrentLogVar
}
set myCurrentLogVar log1
# Set up a switch of logging variable part way through!
after 20000 set myCurrentLogVar log2
for {set i 0} {$i<10} {incr i} {
# Introduce a random delay
after [expr {int(5000 * rand())}]
update ;# Check for the asynch log switch
eval $script $i [clock clicks]
}
Note that in the most common case (where the script fragment is actually just a list of words forming a command prefix), it is better to |
use {*}$script when doing this sort of invocation pattern. It is less general than the eval command, and hence easier to make robust in |
practice. The following 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]
}
However, the last line would now normally be written without eval, like this: |
set var [linsert $var 0 {*}$args] |
