I have the need to check content of very many files for a block of text.
I know the data should match for instance/as an example the following
In the first step, I isolated the interesting data by using sed to print everything between "The list of characters" and the "/"
Now I want to match the entire block by using whats shown above to ensure that the isolated block matches exactly line by line.
If the test block shown above, doesn't match the file containing the isolated and interesting data set a flag to no.
If the test block shown above does match the file containing the isolated and interesting data, set a flag to yes.
I would prefer to do this with sed, awk or ksh. The linux box Im working on has limited perl modules loaded.
The only thing I can think of at this point is loop through the files, then grep each file for every line using the known good data set. That will tell me if a particular lines exists, but wont tell me if the entire block is matched exactly.
Thanks

I figured this would be simple, but I am stuck.
Variable longpath="/dir1/dir2/dir3/filename.stuff.morestuff.garbage"
I want to end up with just "filename.extra.moreextra". So, I want to get rid of the path and .garbage
I want to do this with just ksh internals. So, no sed,grep,awk,expr,... (4 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for lines containing a given pattern
SYNOPSIS
grep [-elnsv] pattern [file] ...
OPTIONS -e-e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
EXAMPLES
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
returned.
