Getting the lines that contains a '/' N times(N given at runtime)
Hi all,
The task I have sounds easy enough but my solution seems too much complicated and I would like some ideas/feedback on how to achieve the same goal with a more elegant solution on HP-UX B.11.23 (a grep with a regexp would be nice, I did not manage to do a working one :/ )
Here is my problem, I have a list of dirname as input and I need to return only the ones that have the depth required (given at runtime)
How I have achieved this so far, please note that the "find . -type d" is just to give you a working example, input will be a flat file and nb_wanted will be set at runtime (here it is set to 2, +1 for the carriage return character):
This solution is pretty slow too :/ Any pointer to a more effective solution would be appreciated.
Lets say I have a file containing string patterns to be looked for inside a file.
I would normaly do :
grep -if MyFilePattern FiletoSearchInto
if I use the -c it gives how many total lines it found out of my whole pattern file, but what if i want grep to report how many times it found each... (4 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.
