Top Forums UNIX for Dummies Questions & Answers Need help with Regex for bash Post 302749959 by Don Cragun on Sunday 30th of December 2012 07:21:47 AM

As Rudi says, we need to know how a regular expression is going to be used to be able to provide you with a regular expression that will match anything. If there is a file containing the strings:
Code:
hexagon-bx.mydomain.com
camera01
hexagon-bx/mydomain.com

it is true that the argument "[a-z0-9\-\[bu]\.*]*$" can be given to grep as a BRE or to grep -E as an ERE to match all three lines.

But, I get the feeling that what is being requested may be a pattern match rather than a BRE or ERE. And nothing that has been suggested will cause the command:
Code:
echo expression

to print the pathnames hexagon-bx.mydomain.com, camera01, nor hexagon-bx/mydomain.com if they are pathnames of existing files in and under the current directory.

We need more context to help.

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
