Match text to lines in a file, iterate backwards until text or text substring matches, print to file
hi all,
trying this using shell/bash with sed/awk/grep
I have two files, one containing one column, the other containing multiple columns (comma delimited).
i'm trying to take each line in file1 and using the original text to match, if no match, iterate backwards one character at time, until it matches first column in file2, loop through all of file2 and print all matching lines where text and any substring matches the first column of file2 to another file. output file3 essentially will have concatenated output of original text from file1 and matching lines from file2
Hi all,
I have a text file and I want to clean up the file by only print those lines start with the date. Is there anyway I can do that?
Thanks

merge
merge(1)merge(1)NAME
merge - three-way file merge
SYNOPSIS
merge [-Llabel1 [-Llabel3]] [-p] [-q] file1 file2 file3
DESCRIPTION
merge incorporates all changes that lead from file2 to file3 into file1. The result goes to standard output if -p is present, into file1
otherwise. merge is useful for combining separate changes to an original. Suppose file2 is the original, and both file1 and file3 are
modifications of file2. Then merge combines both changes.
An overlap occurs if both file1 and file3 have changes in a common segment of lines. On a few older hosts where diff3 does not support the
-E option, merge does not detect overlaps, and merely supplies the changed lines from file3. On most hosts, if overlaps occur, merge out-
puts a message (unless the -q option is given), and includes both alternatives in the result. The alternatives are delimited as follows:
<<<<<<< file1 lines in file1 ======= lines in file3 >>>>>>> file3
If there are overlaps, the user should edit the result and delete one of the alternatives. If the -L label1 and -L label3 options are
given, the labels are output in place of the names file1 and file3 in overlap reports.
DIAGNOSTICS
Exit status is 0 for no overlaps, 1 for some overlaps, 2 for trouble.
