Hi,
I was trying to use this particular option of grep
grep -r 'Search_pattern' *
This command should ideally search all the occurrences of Search_pattern recursively within a directory & print it on shell prompt. But this command is not doing what is expected. It just displays nothin!

Greetings all. :)
I would like to use sed to join all non-blank lines together in a particular file. I was thinking I could do this by simply replacing the terminating, new-line character on every line which is not blank, but I must be missing something in my sed line:

Hi.
I'm new to this forum, my English perhaps is not so good, but here is my question:
In bash you can use ] for tests, and how I understand it the variable names should be expanded automatically. So this should give "yes":

$ ] && echo yes || echo no
no # not giving "yes"
These two... (2 Replies)

Hi All,
I've tried starting syslogd on our hp-ux 11.31 server. However, it is not getting started nor it is updating the syslog file.
There is no space issue also. However, the mail.log file is approx 2GB, can that be of any issue. Please find the details below:

pperl
PPERL(1p) User Contributed Perl Documentation PPERL(1p)NAME
PPerl - Make perl scripts persistent in memory
SYNOPSIS
$ pperl foo.pl
DESCRIPTION
This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes
for each script, allowing many processes to call the script at once.
It works a lot like SpeedyCGI, but is written a little differently. I didn't use the SpeedyCGI codebase, because I couldn't get it to
compile, and needed something ASAP.
The easiest way to use this is to change your shebang line from:
#!/usr/bin/perl -w
To use pperl instead:
#!/usr/bin/pperl -w
WARNINGS
Like other persistent environments, this one has problems with things like BEGIN blocks, global variables, etc. So beware, and try checking
the mod_perl guide at http://perl.apache.org/guide/ for lots of information that applies to many persistent perl environments.
Parameters
$ pperl <perl params> -- <pperl params> scriptname <script params>
The perl params are sent to the perl binary the first time it is started up. See perlrun for details.
The pperl params control how pperl works. Try -h for an overview.
The script params are passed to the script on every invocation. The script also gets any current environment variables, the current working
directory, and everything on STDIN.
Killing
In order to kill a currently running PPerl process, use:
pperl -- -k <scriptname>
You need to make sure the path to the script is the same as when it was invoked.
Alternatively look for a .pid file for the script in your tmp directory, and kill (with SIGINT) the process with that PID.
ENVIRONMENT
pperl uses the PPERL_TMP_PATH environment variable to determine the directory where to store the files used for inter-process
communication. By default, the subdirectory .pperl of the user's home directory is used.
BUGS
The process does not reload when the script or modules change.
$^S is not represented identically with respect to perl, since your script will be run within an eval block
