Top Forums Shell Programming and Scripting Help 'speeding' up this 'parsing' script - taking 24+ hours to run Post 303015126 by Corona688 on Wednesday 28th of March 2018 03:33:59 PM

Running awk once and only once would be so much faster than running awk 180,000,000 times, it'd be done in under a minute, maybe even single digit seconds.

Perl is not faster. If you wrote this code the same way in Perl it'd be just as slow or slower.

Unfortunately, the program you've given doesn't seem to work, so I can't tell what output you want. Could you post the output you want?

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
