Hi, I have an ascii file and i'm just wondering is it possible to edit the file using gawk. I just want to do something simple like print the second field $2, however I don't seem to be able to work out what field seperator to use.
I've tried some code I found in a google search that looks like:
However I'm not sure what the 0x7F stands for in ascii. When I open up the ascii file using an editor like notepad or wordpad the fields look like they are seperated by a tab or spaces. However using code like:

gt5
gt5(1) General Commands Manual gt5(1)NAME
gt5 - a diff-capable 'du-browser'
SYNOPSIS
gt5 [ dir | file | dir file | file file2 ] [options]
DESCRIPTION
gt5 reads the output of du, compares it with a du-log saved by the last run, converts it into HTML and opens the resulting file with a
textbrowser.
If files are given on the commandline they are expected to be (optionally gzip/bzip2-compressed) logfiles of du -akx /some/dir. It is up
to you to take care that the given directories/files represent the same directory. gt5 will show lots of new files if you don't. ;-)
OPTIONS --cut-at float
Files and directories that are below float percent of their parents are not shown. Default is 0.1, gt5 will accept values between
0.01 and 30.
--debug
Turn on debug. Generate HTML files and do not run browser.
--diff-dir directory
Use directory instead of ~/.gt5-diffs/ to read/store du-logs. This switch is ignored if gt5 is only used with files.
--discard
Do not save the current state, in other words: be able to diff against the old state again. This feature is disabled if gt5 is only
used with files.
--help Display brief help.
--link-files
Also insert links to files to access them from within gt5. This can be very handy if your browser is configured to handle the files
MIME-type correctly. This feature is disabled if gt5 is only used with files.
--max-depth int
Do not show anything below a depth of int directories. Default is 5 (also see BUGS below).
--max-lines int
Only consider the int biggest files and directories within the output of du.
--no-diffs
Use this if you are not interested in the history of the directories processed, for example in /tmp.
--save-as file
DEPRECATED, use du -akx or du -ak (see --with-mounts), save the output to a file and run gt5 against one (ore two) of these files
later.
--save-state
Force saving current state, overwriting a previous --discard. (Some people seem to have gt5 aliased to 'gt5 --discard'.)
--verbose
Display messages.
--with-mounts
By default gt5 calls du with -akx to ignore mounted filesystems. Use this to inspect mounted partitions too, i.e. call du with -ak
HELPERS
If gawk or a textbrowser are missing and you want to install them into ~/bin (or /usr/local/bin if you have write access there), gt5 comes
with the following helpers:
--get-gawk
Download, compile and install a copy of gawk.
--get-links
Download, compile and install a copy of links.
--get-links2
Download, compile and install a copy of links2.
--get-elinks
Download, compile and install a copy of elinks.
TEXTBROWSERS
It is recommended to use links with gt5. Other textbrowsers are also possible but there are several good reasons why links is given prior-
ity over the others:
elinks:
links is much faster on startup/exit
lynx: does not honor a documents coloring
netrik:
no colors, unfavourable cursor navigation
retawq:
no colors, can't handle <a name>-tags
w3m: Version 0.5.2 and later are known to work. Older versions experienced unfavourable handling of <a name>-tag, unfavourable cursor
navigation and no colors
Only links/links2, elinks and lynx are now considered usable (and also chosen in that order). See ENVIRONMENT/GT5_BROWSER below.
FILES
~/.gt5.html
contains a copy of the last run
~/.gt5-diffs/
compressed du-logs are stored here
ENVIRONMENT
GT5_BROWSER
force using a (specific) textbrowser
GT5_CHARSET
force using a (specific) charset for HTML header instead of using $LANG
GT5_DEBUG_DIR
Directory where to write gt5.debug* data if --debug option is set.
BUGS
Directories at depth max-depth are not browsable and so look like files.
