Thank you it works and I edited my previous post. I also have a similar question for this code then:
.pdb.txt file looks like this:
You have 7 lines of r<x> where x is a number from 1 to 100 and 7 occurrences of ALA. However, how I could change grep to awk in the code so it would count 4 ALA instead of 7?

.... | awk '{print date $0}' (4 Replies)

So while this seemed totally trivial it turned out to be much more difficult than I had thought.
I have a file with 3 rows, and I "just" want to add each field n number of times. E.g.
> cat file.txt
0.5
-0.1
0.6
for n=3 into:
cat newfile.txt
0.5 0.5 0.5
-0.1 -0.1 -0.1
0.6 0.6 0.6

Hello,
Giving those commands:
cat > myfile

^D
cat myfile | awk '{ s=s+$1 ; print s}'
The output is:
1

It seems like this command iterates each time on a different row so $1 is the first field of each row.. But what caused it to refer to each row ?.
What I mean... (3 Replies)

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
