I want to grep from a file an exact character match.
I tried grep -c "$a $b" $file
where a=6 and b=2
the problem is that I get: 6 2 and 6 20
I just need a count of the occurrence.
I'm using the Bourne shell.
I've also tried grep -c '$a $b' $file;
not sure how to do this - any suggestions? (3 Replies)

Please help. This simple problem is really stumping me.
Is there are way to find absolute pathnames for all files on your system that are longer than 100 characters?
I'm using bash shell to attempt it, but have come up with nothing so far.

cut
CUT(1) General Commands Manual CUT(1)NAME
cut - select out columns of a file
SYNOPSIS
cut [ -b | -c] list [file...]
cut -f list [-d delim] [ -s]
OPTIONS -b Cut specified bytes
-c Select out specific characters
-d Change the column delimiter to delim
-f Select out specific fields that are separated by the
-i Runs of delimiters count as one
-s Suppres lines with no delimiter characters, when used
EXAMPLES
cut -f 2 file # Extract field 2
cut -c 1-2,5 file # Extract character columns 1, 2, and 5
cut -c 1-5,7- file # Extract all columns except 6
DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched"
Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa-
rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be
specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires
the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses
only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man-
ual page.
