You can use an if condition to check if length of col2 is greater than 59 chars and print accordingly:-
if [ ${#col2} -gt 59 ]
then
# print next line
else
# print same line
fi

perl -e 'use POSIX qw/strftime/; @x = split /\//, $ARGV[0]; print strftime("%m/%d/%y",localtime)'

assuming that sendmail -t $tmp does work to send email. I do not see where the $uid variable gets used to address email. Oh well.
bash or ksh example using your code fragment:

#!/bin/bash...

A dozen descriptors isn't very many. I'd just keep them open.

<?php
$date = date();
echo "Today's date is $date";
?>


Note the double quotes. PHP will evaluate the variable in strings with double quotes (not single quotes).

Ah, so command1 command2 command3 must be executed sequentially, but the different instances can go in parallel.

for X in 1 2 3 4 5
do
( command1 ; command2 ; command3 ) &
done

wait...

Use the taskset command. You need some privilege to use it.

The syntax is:

for i in something
do
taskset [cpumask] command $i &
taskset [cpumask] command2 $i &
taskset [cpumask] ...

That's decided by the operating system. You run n commands simultaneously and if there's enough CPU's, it will run them concurrently.

for X in 1 2 3 4 5
do
command &
done

wait

Try this:

find . -maxdepth 1 -type d -print0 | xargs -0 -n 1 du -hs | while read SIZE FILE
do
echo "$FILE" "[$SIZE]"
done

Okay.

find . -maxdepth 1 | xargs -I {} du -hs | while read SIZE FILE
do
echo "$FILE" "[$SIZE]"
done

Do you mean fuser?

just supply the filename(s) that exactly match names inside the tarball on your tar -x argument list.
e.g.

$ gzcat foo.tgz | tar -xf - exact/path/to/filename1

Assuming that's the posted input try this...
sort -k6,6nr file

Try adding the regex type option:


find / -regextype posix-egrep -regex "/.{0,50}.*" -maxdepth 1


According to the man page on my system (SuSE) the default is emacs. I'm not sure how emacs...

$ re_pattern="'.*\.c\$'"
$ re_args='\! -regex '"$re_pattern"
$ eval find . "$re_args" -type f
... <my list of non-C source files here> ...

How about a nested find command...
find start_dir -name "dirname_regexp" -type d -exec find {} -name "somefile" \;

If you have Linux, the -regex option is available, but not with standard find, no.

You could also just pipe its output through egrep which should be able to handle it fine.

The find command can do what you want, pretty sure.

$ find /path/to/dir/ '!' -user validuser
/path/to/dir/inside/filenotbelongingtovaliduser
...
$

Putting it in quotes causes it to pass it as one single argument. It's not perl that has to understand the newlines, it's the shell.

Keeping everything as one giant string like that is subject to...
