Given a csv file with 40 columns with name, address, hometown etc.
I use a bash command in 1 line which:
1. gets the address column and pipes that to
2. grep the first digit and everything that follows
Command:
It generates the results I want, except in the case that the grep result is empty.
When there is no digit present, the command prints nothing and the result will end up with 1 line less. That gives a problem in further processing. I need the same number of lines as in the original file. So in that case I'd like to insert a new line for further processing.
And the code needs to be in one line
I found that when I used a variable to receive the result from a command execution, the newline characters were removed from the variable.
For example, I ran
$ ret=`ls -l`
$ echo $ret
Then, I saw:

I have successfully used regexp and sed to insert a newline before or after a line containing a matched pattern /WORD/. However, I want to insert a newline immediately following /WORD/ and not after the -line- containing the pattern matched. I can match a pattern, but it is matched via a wild card... (2 Replies)

Hi,
I use sed to insert text at beginning of a file. But sed inserts a newline after my text that I do not need. For example, I want to insert "foo" at the beginning of my file:
> cat myfile
This is first line.
> sed -i '1i\foo' myfile
> cat myfile
foo
This is first line.

Hi
While trying to do a search on solaris, the grep results seems to be appearing on the same line instead of the new line.

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.
