Hello all,
I am having trouble with setting up a regular expression used with egrep. My script reads an input file a line at a time. I would like the egrep command to search for the following pattern: server name at the beginning of the line, then one or more spaces, and then a pound sign.

Hi
I am writing a script which should read a file and search for certain strings 'approved' or 'removed' and retain only those lines that contain the above strings.
Ex: file name 'test'
test:

waiting for approval package

It sounds a bit confusing but what I have is a text file like the example below (without the Line1, Line2, Line3 etc. of course) and I want to move every group of characters into a new line after each space.
Example of text file;

I'm trying to extract all the lines between 2 strings (including the lines containing the strings)
To make the strings unique I need to include white space if possible. I'm not certain how to do that.
sed -n '/ string1 /,/string2/p' infile > outfile & (4 Replies)
I'm trying to remove all of the empty lines at the end of a Tab delimited file. They have no data just tabs.
I've tried may things, here are a couple:
sed /^\t.\t/d File1 > File2
sed /^\t{44}/d File1 > File2
What am I missing? (9 Replies)
Hi - I have req to join broken lines and remove empty lines but should NOT be in one line. It has to be as is line by line. The challenge here is there is no end of line/start of line char.

GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.
I am assuming that sed, awk or even perl could do what I need.
I have an application that adds extra blank page feeds, for multiple reports, when... (7 Replies)

DIFF(1) General Commands Manual DIFF(1)NAME
diff - differential file comparator
SYNOPSIS
diff [ -acefmnbwr ] file1 ... file2
DESCRIPTION
Diff tells what lines must be changed in two files to bring them into agreement. If one file is a directory, then a file in that directory
with basename the same as that of the other file is used. If both files are directories, similarly named files in the two directories are
compared by the method of diff for text files and cmp(1) otherwise. If more than two file names are given, then each argument is compared
to the last argument as above. The -r option causes diff to process similarly named subdirectories recursively. When processing more than
one file, diff prefixes file differences with a single line listing the two differing files, in the form of a diff command line. The -m
flag causes this behavior even when processing single files.
The normal output contains lines of these forms:
n1 a n3,n4
n1,n2 d n3
n1,n2 c n3,n4
These lines resemble ed commands to convert file1 into file2. The numbers after the letters pertain to file2. In fact, by exchanging `a'
for `d' and reading backward one may ascertain equally how to convert file2 into file1. As in ed, identical pairs where n1 = n2 or n3 = n4
are abbreviated as a single number.
Following each of these lines come all the lines that are affected in the first file flagged by `<', then all the lines that are affected
in the second file flagged by `>'.
The -b option causes trailing blanks (spaces and tabs) to be ignored and other strings of blanks to compare equal. The -w option causes
all white-space to be removed from input lines before applying the difference algorithm.
The -n option prefixes each range with file: and inserts a space around the a, c, and d verbs. The -e option produces a script of a, c and
d commands for the editor ed, which will recreate file2 from file1. The -f option produces a similar script, not useful with ed, in the
opposite order. It may, however, be useful as input to a stream-oriented post-processor.
The -c option includes three lines of context around each change, merging changes whose contexts overlap. The -a flag displays the entire
file as context.
Except in rare circumstances, diff finds a smallest sufficient set of file differences.

SEE ALSO cmp(1), comm(1), ed(1)DIAGNOSTICS
Exit status is the empty string for no differences, for some, and for trouble.
BUGS
Editing scripts produced under the -e or -f option are naive about creating lines consisting of a single `.'.
When running diff on directories, the notion of what is a text file is open to debate.
