Hello,
Could you put some light on this:
It's executed on AIX if that matters. The man page is not very verbose. What I've figured out myself is that cut -c removes chars from string (which is stated in manpage actually ). I've found a few examples via Google. So after -c is the chars position I suppose. Also it looks like that without the trailing dash cut just prints the char at this position.
Here is what I don't understand:
1) "ref_categorie=" is 14 chars, why -c14- leaves also the '='?
2) What's the difference between -c15- and -c1-15- ? They do the same in my case, but maybe there is something that I'm missing.
Thank you very much for your help!

I have a start|stop|restart script for a custom app we have. After it tries to stop our process the correct way, it checks to see if it's gone, if not it tries to kill it, if that doesn't work kill -9.

Hi all,
I'm trying to extract string from variable in BASH. That's probably trivial for grep but I couldn't figure it out.

cut
CUT(1) BSD General Commands Manual CUT(1)NAME
cut -- select portions of each line of a file
SYNOPSIS
cut -b list [-n] [file ...]
cut -c list [file ...]
cut -f list [-d delim] [-s] [file ...]
DESCRIPTION
The cut utility selects portions of each line (as specified by list) from each file and writes them to the standard output. If the file
argument is a single dash ('-') or no file arguments were specified, lines are read from the standard input. The items specified by list can
be in terms of column position or in terms of fields delimited by a special character. Column numbering starts from 1.
list is a comma or whitespace separated set of increasing numbers and/or number ranges. Number ranges consist of a number, a dash (-), and a
second number and select the fields or columns from the first number to the second, inclusive. Numbers or number ranges may be preceded by a
dash, which selects all fields or columns from 1 to the first number. Numbers or number ranges may be followed by a dash, which selects all
fields or columns from the last number to the end of the line. Numbers and number ranges may be repeated, overlapping, and in any order. It
is not an error to select fields or columns not present in the input line.
The options are as follows:
-b list The list specifies byte positions.
-c list The list specifies character positions.
-d string Use the first character of string as the field delimiter character. The default is the <TAB> character.
-f list The list specifies fields, separated by the field delimiter character. The selected fields are output, separated by the field
delimiter character.
-n Do not split multi-byte characters.
-s Suppresses lines with no field delimiter characters. Unless specified, lines with no delimiters are passed through unmodified.
EXIT STATUS
cut exits 0 on success, 1 if an error occurred.
SEE ALSO paste(1)STANDARDS
The cut utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
