Driver,
My point was that in awk you can use start/end pairs. i.e. two patterns or conditions sepated by a comma. All you have to do is determine what the conditions are.
My post works with the sample supplied. But with the sample you have supplied, the end condition might be "/^}$/" , i.e. a line that is one "}" on its own with no whitespace. So you would have...
awk '/sub foo/,/^}$/' file
...which could be the simplest solution, but perhaps more work is needed.
It would be more efficient to use "exit" to stop reading the file when the end condition is reached. The idea of counting matched braces can be coded more simply as ....
awk '/sub foo/,0 {print;b+=gsub("\{","{");b-=gsub("\}","}");if(b==0)exit}' file

FIXPS(1) FSF FIXPS(1)
NAME
fixps - sanitize PostScript files
SYNOPSIS
fixps [OPTIONS] FILE
DESCRIPTION
Try to fix common PostScript problems that break postprocessing.
OPTIONS
-h, --help
display this help and exit
-v, --version
display version information and exit
-q, --quiet
don't print informational messages
-o, --output=FILE
save result in FILE. If FILE is `-', send to stdout
-f, --force
force full rewrite by ghostscript
-n, --no-fix
don't fix the FILE, but still honor `-o'
-c, --check, --dry-run
don't perform any action
Fixes:
- Remove junk before and after PostScript content - Use only Unix end of lines (
) - Remove empty lines - Fix Apple prologue (fix-
macps) - Fix FrameMaker prologue (fixfmps) - Fix CorelDraw prologue (fixnt) - Fix Windows NT 3.5/4.0 prologue (fixnt) - Fix Windows
95 prologue - Ensure there is a `%%BeginSetup/%%EndSetup' section - Removes Canvas' extraneaous `%%EndDocument:' comments - Split
too long lines
If the FILE seems really in a bad state, ghostscript may be used to perform a full rewrite. The output might then be significantly bigger,
but much safer.
