Code:
SOMTHING_NICK_SOMTHING 
hellorichwhatareyoudoing 
SOMTHING.NICK.SOMTHING 
somthing_NICK_somthing 
HELLO-NICK-HELLO

not quite what I was expecting Smilie, My fault probably for not being clear enough with the requirement:

Code:
richard@opensolaris:~/share/cleaner$ echo "RICH_SOMTHING" | sed 's/\(.*[_.-]\)\([Rr][iI][Cc][Hh]\)\([_.-].*\)/\1NICK\3/g'
RICH_SOMTHING

richard@opensolaris:~/share/cleaner$ echo "SOMTHING@RICH" | sed 's/\(.*[_.-]\)\([Rr][iI][Cc][Hh]\)\([_.-].*\)/\1NICK\3/g'
SOMTHING@RICH

basically it's a case of "if there are any letters (with no spaces) directly to the left or right of the string I'm replacing, don't replace it" so the following must be left alone:

HELLORICHHELLO
HELLORICH
RICHHELLO

anything other than the above is fair game Smilie with the added condition that 'if you're doing a replace and the string being replaced is lower case, replace with lowercase, if uppercase, replace with uppercase Smilie

Nearly got it...

Code:
richard@opensolaris:~/share/cleaner$ echo "@rich" | sed 's/\(.*[_.-.@]\)\(rich\)\([_.-.@].*\)/\1NICK\3/ig'
@rich
richard@opensolaris:~/share/cleaner$ echo "@RICH@" | sed 's/\(.*[_.-.@]\)\(rich\)\([_.-.@].*\)/\1NICK\3/ig'
@NICK@

how to set a variable to accept alpha-numeric characters?

I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics? Thanks! Brent (3 Replies)

IMPRESSIVE-GETTRANSITIONS(1)				      Debian GNU/Linux manual				      IMPRESSIVE-GETTRANSITIONS(1)

NAME

       impressive-gettransitions - Generate Impressive info scripts for LaTeX presentations

SYNOPSIS

       impressive-gettransitions FILE.tex

DESCRIPTION

       A simple script to produce a .info file for use with Impressive, using special comments in a LaTeX/Beamer file. FILE.tex is a file to be
       parsed into .info file. For each /fullpath/blah.tex /fullpath/blah.pdf.info gets produced.

SYNTAX

       In the LaTeX document, impressive-gettransitions counts the pages to determine the PDF slide number of each one.

       The simpler page changes are automatically detected, that is:
	   egin{frame} and:
	   pause

       Other, more elaborated page changes must be noted with a %O comment:
	   item<1-> Foo
	   item<2-> Bar %O

       The transition to apply can be specified in a %O comment:
	   egin{frame} %O SlideUp

OPERATION

       When the .info file corresponding to the LaTeX document already exist, impressive-gettransitions does not clear it, but only adds the
       transitions if finds to it.

       Thus, if you modified your document in a way that requires to completely replace the transitions, manually clear the PageProps section of
       the .info file. This can be done by running the following sed command:
	   sed -i -e "/^PageProps = {/,/^}/d" FILE.info
