Top Forums Shell Programming and Scripting How to convert 24 hour time to 12 hour timing? Post 302762677 by Don Cragun on Tuesday 29th of January 2013 01:15:47 AM

The above suggestions don't strip off input fields 3 and 4. If you want something matching the output you said you want, try something like:
Code:
awk '{  split($2, df, /:/)
        $2 = sprintf("%d:%02d:%02d %sM",
                df[1] > 12 ? df[1] - 12 : df[1] ? df[1] : 12,
                df[2], df[3], df[1] >= 12 ? "P" : "A")
        print $1, $2
}' file

I misread Pamu's suggested script. It does strip off the last two input columns, but produces zero-filled hours where the requested output didn't have space or zero fill for hours less than 10.

STRIP(1)						    BSD General Commands Manual 						  STRIP(1)

NAME
strip -- discard information from ELF objects SYNOPSIS
strip [-d | -g | -S | --strip-debug] [-h | --help] [--only-keep-debug] [-o outputfile | --output-file=outputfile] [-p | --preserve-dates] [-s | --strip-all] [--strip-unneeded] [-w | --wildcard] [-x | --discard-all] [-I format | --input-target=format] [-K symbol | --keep-symbol=symbol] [-N symbol | --strip-symbol=symbol] [-O format | --output-target=format] [-R sectionname | --remove-section=sectionname] [-V | --version] [-X | --discard-locals] file ... DESCRIPTION
The strip utility is used to discard information from ELF objects. The strip utility supports the following options: -d | -g | -S | --strip-debug Remove debugging symbols only. -h | --help Print a help message and exit. --only-keep-debug Remove all content except that which would be used for debugging. -o outputfile | --output-file=outputfile Write the stripped object to file outputfile. The default behaviour is to modify objects in place. -p | --preserve-dates Preserve the object's access and modification times. -s | --strip-all Remove all symbols. --strip-unneeded Remove all symbols not needed for further relocation processing. -w | --wildcard Use shell-style patterns to name symbols. The following meta-characters are recognized in patterns: ! If this is the first character of the pattern, invert the sense of the pattern match. * Matches any string of characters in a symbol name. ? Matches zero or one character in a symbol name. [ Mark the start of a character class. Remove the special meaning of the next character in the pattern. ] Mark the end of a character class. -x | --discard-all Discard all non-global symbols. -I format | --input-target=format These options are accepted, but are ignored. -K symbol | --keep-symbol=symbol Keep the symbol symbol even if it would otherwise be stripped. This option may be specified multiple times. -N symbol | --strip-symbol=symbol Remove the symbol symbol even if it would otherwise have been kept. This option may be specified multiple times. -O format | --output-target=format Set the output file format to format. For the full list of supported formats, please see the documentation for function elftc_bfd_find_target(3). -R sectionname | --remove-section=sectionname Remove the section named by the argument sectionname. This option may be specified multiple times. -V | --version Print a version identifier and exit. -X | --discard-locals Remove compiler-generated local symbols. DIAGNOSTICS
The strip utility exits 0 on success, and >0 if an error occurs. SEE ALSO
