I have a sample text file like this.
I want to delete the line only when the 4th field is empty. Here the delimiter is |^. Here 2nd line is to be deleted. First line is the heading. One condition here but, if the 3rd column is empty it shouldn't delete that line. Deletion should happen only if the 4th column is empty. I tried this which is not solving the real purpose.

I have a large(ish) pipe delimited file.
The last line of the file contains a total row count and a checksum:

After making other adjustments to the file, I need to strip out the checksum and apply a new value - I have a script to generate the checksum and 'cat' it... (3 Replies)

Hello,
I have a large database with the following structure:

catman
CATMAN(8) Manual pager utils CATMAN(8)NAME
catman - create or update the pre-formatted manual pages
SYNOPSIS
catman [-dhV] [-M path] [-C file] [section] ...
DESCRIPTION
catman is used to create an up to date set of pre-formatted manual pages known as cat pages. Cat pages are generally much faster to dis-
play than the original manual pages, but require extra storage space. The decision to support cat pages is that of the local administra-
tor, who must provide suitable directories to contain them.
The options available to catman are the manual page hierarchies and sections to pre-format. The default hierarchies are those specified as
system hierarchies in the man-db configuration file, and the default sections are either the colon-delimited contents of the environment
variable $MANSECT or the standard set compiled into man if $MANSECT is undefined. Supplying catman with a set of whitespace-delimited sec-
tion names will override both of the above.
catman makes use of the index database cache associated with each hierarchy to determine which files need to be formatted.
OPTIONS -d, --debug
Print debugging information.
-M path, --manpath=path
Specify an alternate colon-delimited manual page hierarchy search path. By default, this is all paths indicated as system hierar-
chies in the man-db configuration file.
-C file, --config-file=file
Use this user configuration file rather than the default of ~/.manpath.
-h, --help
Print a help message and exit.
-V, --version
Display version information.
ENVIRONMENT
MANSECT
If $MANSECT is set, its value is a colon-delimited list of sections and it is used to determine which manual sections to search and
in what order.
MANPATH
If $MANPATH is set, its value is interpreted as the colon-delimited manual page hierarchy search path to use.
FILES
/etc/manpath.config
man-db configuration file.
/usr/man/index.(bt|db|dir|pag)
A traditional global index database cache.
/var/catman/index.(bt|db|dir|pag)
An alternate or FSSTND compliant global index database cache.
