> Can I mix bash with perl in a program?
Yes, both ways;
$ perl -e 'print "Hello World!\n"'
Hello World!
$ cat ls.pl
#!/usr/bin/perl -w
use strict;
print `ls @ARGV`
$ ./aa -r -t -l /usr | tail -4

echo -> print()
read -> read() or readline()
etc. -> get a perl book or read an online tutorial

You can do that but that only affects the current shell, so
`cd /usr/local`; won't help you, use chdir() in perl instead.
For the same reason this doen't work either:
$ pwd
/Net
$ perl -e 'chdir("/usr/local");'
$ pwd
/Net
$
> - ls : List the contents of the current directory.
either:
@list = `ls -1 /usr/local`;
$list = `ls -1 /usr/local`;
you can also use
opendir(); readdir(), there is an example in man perlfunc under readdir.

man perlfunc is your friend.

`touch zzz`
see example in man perlfunc under utime

As in c, use unlink(), man perlfunc

`cp xxxx`;

As in c, use rename(), man perlfunc

Ask on one of the debian mailing lists.
