Top Forums Shell Programming and Scripting How to count pattern in column Post 302148908 by ahjiefreak on Tuesday 4th of December 2007 05:33:09 AM

Hi Franklin,

I agree with what you explained. But given the fact if I have one line consist of different patterns such as "`" (the one you showed me) and "$".
or even more other patterns,

If that is the case how can I use NF to differentiate these characters.

For your information, my input is a line of statements which is something like below:-

halo`world$$``

If using the method you showed me, we could have one NF tricked one at a time. How could we represent for both patterns in this case.

Please advise. Hope you could get my meaning. Thanks.

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME
colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
awk(1), column(1), cut(1), paste(1) HISTORY
The colrm command appeared in 3.0BSD. BSD
August 4, 2004 BSD
