Full Discussion: Using awk with the date command and escape characters

Thank you so much!

Both the perl and the while read solution worked great! I'll let you know if one runs faster than the other as I will be running this on approximately 1 million lines.

---------- Post updated at 01:02 PM ---------- Previous update was at 08:49 AM ----------

Ok, so I ran both the Perl and the "while read" code blocks on a 309MB log file that had 6,397,194 lines. While both code blocks performed the same end result, the Perl block of code performed exponentially faster, so I had to use that instead of the while read. I waited about 10 minutes on the "while read" block and it was still going. The Perl block finished under 3 minutes. So I ended up using the Perl block in my script.

Thank you both for your help!

pydf

PYDF(1) 						      General Commands Manual							   PYDF(1)

NAME

       pydf - report colourised filesystem disk space usage

SYNOPSIS

       pydf [options] [file]

DESCRIPTION

       pydf  is a python script that displays the amount of disk space available on the mounted filesystems, using different colours for different
       types of filesystems. Output format is completely customizable.

       If an optional
	      file argument is given, pydf displays just information about filesystem containing the file(s), otherwise  it  displays  information
	      about all mounted filesystems.

OPTIONS

       --help Show summary of options.

       -v, --version
	      Show version of program.

       -a, --all
	      include filesystems having 0 blocks

       -h, --human-readable
	      print sizes in human readable format (e.g., 133K 2341M 2448G)

       -H, --si
	      likewise, but use powers of 1000 not 1024

       --block-size=SIZE
	      use SIZE-byte blocks

       -k, --kilobytes
	      like --block-size=1024

       -i, --inodes
	      show information about inodes instead of blocks

       -l, --local
	      limit listing to local filesystems

       -m, --megabytes
	      like --block-size=1048576

       -g, --gigabytes
	      like --block-size=1073741824

       --blocks
	      use filesystem native block size

       --bw   do not use colours

       --mounts=FILE
	      file  to	get  mount  information  from.	 On normal linux system, only /etc/mtab or /proc/mounts make sense.  Use /proc/mounts when
	      /etc/mtab is corrupted or inaccessible (the output looks a bit weird in this case though)

       -B, --show-binds
	      Show also mount --bind mounted filesystems.

BUGS

       When running with python3, mountpoints with out-of-locale non ASCII names will not be displayed (due to	inability  of  os.statvfs  to  use
       bytes instead of strings).

FILES

       /etc/pydfrc
	      main configuration file

       ~/.pydfrc
	      per-user configuration file
