Shell Programming and Scripting

dear all,

on solaris10 for x86 i am trying to modify the creation date of a postscript file with sed in a csh script. sed is driving me crazy though...i think due to the spaces in the string i am trying to substitute??

part of the postscript file:
%!PS-Adobe-3.0
%---------------------------- Header --------------------------
%%Title: Default Title
%%Creator: Default Creator
%%CreationDate: Mon Feb 2 15:31:04 2009 - there are 2 spaces in front of the 2 originally!!

if i do:

Code:

set created = `more $PATH/file.ps | grep CreationDate | cut -d " " -f 2,3,4,5,6,7`
echo $created

it will give me:
Mon Feb 2 15:31:04 2009 though it should be "Mon Feb 2 15:31:04 2009" (there are 2 spaces in front of the day of the month if it is less than 10)
if i do:

Code:

echo $created | awk '{if ($3<10) $3=" "$3}{print}'

it will give me the same thing
and to make that complete if i want to declare the new date with

Code:

set new = "Tue Jan  2 14:14:23 2008"
echo $new

....guess what? same missing space?!

i was also looking for a tool within psutils but didn't find anything - does anyone have an idea how i could make the sed "s/${created}/${new}" file.ps work or any other way to manipulate the date of creation?
thank you very much from germany

Use quotes

Code:

# echo $new
Tue Jan 2 14:14:23 2008
# echo "$new"
Tue Jan  2 14:14:23 2008

You don't need more:

Code:

grep CreationDate $PATH/file.ps | cut -d " " -f 2,3,4,5,6,7

Quote the variable:

Code:

echo "$created"

No missing space, just missing quotes.

what did the trick was:

Code:

set created = "`head -6 %PATH/file.ps | grep CreationDate  | cut -c  17-40`"

now sed will swallow it with the desired new date

Code:

more %PATH/file.ps | sed -e "s/${created}/${new_date}/" > %PATH/file_mod.ps

cheers
