Top Forums Shell Programming and Scripting Problems extracting word using SED Post 302587644 by rbatte1 on Thursday 5th of January 2012 12:27:01 PM

Perhaps a dull solution, but you could convert every space to a newline and then use grep:
Code:
cat $filesname | tr " " "^J" | grep "^PS_"

Note, to generate the ^J as a single character, use the key sequence Cntrl-v Cntrl-j
The grep string is just as plain text so it is looking for start of line (the ^) then PS_


Probably not the most efficient way, but it might get you going if your just after a once only hit.



I hope that this helps,

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera- tion are not performed. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
