Using egrep, I am finding matching records in file b, then outputing feilds of both into another file.

Hi--
I'm trying to figure out how to use cat more wisely. I have the following command, which works, but I'd like to understand how to get it to work more clearly and efficiently.
cat 'my file.001' 'my file.002' 'my file.003' 'my file.004' 'my file.005' 'my file.006' 'my file.007' 'my... (6 Replies)
Hello!
I have one strange question - let's say I have a long, multiple-line string displayed on the terminal using echo, and I would like to make a carriage return to the beginning of this string, no to the beginning of the last line - is something like that possible? I would like to be able to... (1 Reply)
I have a number of files in a directory named like this:

TIA

Hi everyone,
I'm new to the forums, as you can probably tell... I'm also pretty new to scripting and writing any type of code.
I needed to know exactly how I can grep for multiple strings, in files located in one directory, but I need each string to output to a separate file.
So I'd... (19 Replies)

Is there any way to do a cat * where it shows the name of each file in the process? Similar to what more does below?

I am looking for help in processing of those options: '-n' or '-p'
I understand what they do and how to use them.
But, I would like to use them with more than one file (and without any shell-loop; loading the 'perl' once.)
I did try it and -n works on 2 files.
Question is:

merge
merge(1) General Commands Manual merge(1)NAME
merge - three-way file merge
SYNOPSIS
file1 file2 file3
DESCRIPTION
combines two files that are revisions of a single original file. The original file is file2, and the revised files are file1 and file3.
identifies all changes that lead from file2 to file3 and from file2 to file1, then deposits the merged text into file1. If the option is
used, the result goes to standard output instead of file1.
An overlap occurs if both file1 and file3 have changes in the same place. prints how many overlaps occurred, and includes both alterna-
tives in the result. The alternatives are delimited as follows:
lines in file1
lines in file3
If there are overlaps, edit the result in file1 and delete one of the alternatives.
This command is particularly useful for revision control, especially if file1 and file3 are the ends of two branches that have file2 as a
common ancestor.
EXAMPLES
A typical use for is as follows:
1. To merge an RCS branch into the trunk, first check out the three different versions from RCS (see co(1)) and rename them for
their revision numbers: 5.2, 5.11, and 5.2.3.3. File 5.2.3.3 is the end of an RCS branch that split off the trunk at file 5.2.
2. For this example, assume file 5.11 is the latest version on the trunk, and is also a revision of the "original" file, 5.2.
Merge the branch into the trunk with the command:
3. File 5.11 now contains all changes made on the branch and the trunk, and has markings in the file to show all overlapping
changes.
4. Edit file 5.11 to correct the overlaps, then use the command to check the file back in (see ci(1)).
