The msort utility was in the Debian repository. See the web page noted in the script for a PDF of documentation and other details ... cheers, drl

"Non-standard" extant tools often: are general, have the
simplest, most appropriate interface, and are convenient
alternatives in the context of equally useful, but

The knowledge that such tools exist can be of advantage for
solving future similar, but specifically different problems.
Hi--
Ok. I have now found that:
find -x -ls
will do what I need as far as finding all files on a particular volume. Now I need to sort the results by the file's modification date/time.
Is there a way to do that?
Also, I notice that for many files, whereas the man for find says ls is... (8 Replies)
Hi All
I have a flat text file. Each line in it contains a "/full path/filename". The last three columns are predictable, but directory depth of each line varies.
I want to sort on the last three columns, starting from the last, 2nd last and 3rd last. In that order. The last three columns... (6 Replies)
Here is the code, but the list is not sorted properly (alphabetically)?

Hi,
Am running the command below to search for files that contains a certain string.
grep -il "shutdown" `find . -type f -mtime -1 -print` | grep "^./scripts/active"
How do I get it to do a ls -l on the list of files? I tried doing ls -l `grep -il "shutdown" `find . -type f -mtime -1... (5 Replies)
Hello and thanks in advance for any help anyone can offer me
I'm trying to learn the find command and thought I was understanding it... Apparently I was wrong. I was doing compound searches and I started getting weird results with the -size test. I was trying to do a search on a 1G file owned by... (14 Replies)
Hi Folks -

Could you please advise on the following: I have two space-delimited files with 9 and 10 columns, respectively, with exactly the same values in column 1. However, the order of column 1 differs between the two files, so I want to sort both files by column 1, so that I can align them and... (6 Replies)
Using the 'strings' command and piping the result to 'sort' is producing strange results. I get block of lines that begin with asterisks, then a block that begins with some text, then more lines that begin with asterisks. The actual content is correct - lines beginning with asterisks is the... (5 Replies)

shell-quote
SHELL-QUOTE(1) User Contributed Perl Documentation SHELL-QUOTE(1)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
