Full Discussion: Printing Number of Fields with the line number
Top Forums Shell Programming and Scripting Printing Number of Fields with the line number Post 302591918 by Android Control on Saturday 21st of January 2012 03:06:45 PM

Be careful with your expectations, as your results will actually be;

1 4
2 4
3 4

Even though the first two lines have nothing after the last "|" there will still be a count of 4 for each line - even for an empty field. You will need to manage that by either not adding the trailing "|" or checking for "relevant content" of each field. Something like, if a field = /^$/ then take 1 away from the value of NF.

If you have a consistent number of "|" then your NF will always be the same regardless of what is between them.

nntpsend.ctl

NNTPSEND.CTL(5) 						File Formats Manual						   NNTPSEND.CTL(5)

NAME

       nntpsend.ctl - list of sites to feed via nntpsend

DESCRIPTION

       The file <--prefix=PREFIX at configure>/nntpsend.ctl specifies the default list of sites to be fed by nntpsend(8).

       Comments begin with a number sign (``#'') and continue through the end of the line.  Blank lines and comments are ignored.  All other lines
       should consist of four fields separated by a colon.

       The first field is the name of the site as specified in the newsfeeds(5) file.

       The second field should be the hostname or IP address of the remote site.

       The third field, if non-empty, specifies the default head truncation size of site's batchfile.  If this field is empty,	no  truncation	is
       performed.  If this field is of the form ``maxsize-truncsize'' then it is passed to shrinkfile as ``-m maxsize -s truncsize'', otherwise is
       of the form ``truncsize'' then it is passed as ``-s truncsize''.

       The fourth field specifies some default flags passed to innxmit(8).  The flag ``-a'' is always given to innxmit and need not  appear  hear.
       If no ``-t timeout'' flag is given in this field and on the nntpsend command line, ``-t 180'' will be given to innxmit.
