Hi.

Standard cut accepts a single character for a delimiter. The awk interpreter allows a regular expression to be specified. So, for example, you could approximate the cut of field 2 of your sample data with:
Code:
#!/usr/bin/env sh

# @(#) a1       Demonstrate awk field splitting with a regular expression.

set -o nounset
echo

## Use local command version for the commands in this demonstration.

echo "(Versions used in this script displayed with local utility "version")"
version bash awk cat

echo
echo " Results of printing field 2, as cut might do it:"

awk '
BEGIN   { FS = " *[|][|] *" }
        { print $2 }
' data1 |
cat -vet

exit 0

Producing:
Code:
% ./a1

(Versions used in this script displayed with local utility version)
GNU bash, version 2.05b.0(1)-release (i386-pc-linux-gnu)
GNU Awk 3.1.4
cat (coreutils) 5.2.1

 Results of printing field 2, as cut might do it:
mango$

You could remove the " *" from the regular expression, but then you would get extra spaces around the output fields ... cheers, drl

CUT(1)                                                             User Commands                                                            CUT(1)

NAME

       cut - remove sections from each line of files

SYNOPSIS

       cut OPTION... [FILE]...

DESCRIPTION

       Print selected parts of lines from each FILE to standard output.

       With no FILE, or when FILE is -, read standard input.

       Mandatory arguments to long options are mandatory for short options too.

       -b, --bytes=LIST
              select only these bytes

       -c, --characters=LIST
              select only these characters

       -d, --delimiter=DELIM
              use DELIM instead of TAB for field delimiter

       -f, --fields=LIST
              select only these fields;  also print any line that contains no delimiter character, unless the -s option is specified

       -n     (ignored)

       --complement
              complement the set of selected bytes, characters or fields

       -s, --only-delimited
              do not print lines not containing delimiters

       --output-delimiter=STRING
              use STRING as the output delimiter the default is to use the input delimiter

       -z, --zero-terminated
              line delimiter is NUL, not newline

       --help display this help and exit

       --version
              output version information and exit

       Use  one,  and only one of -b, -c or -f.  Each LIST is made up of one range, or many ranges separated by commas.  Selected input is written
       in the same order that it is read, and is written exactly once.  Each range is one of:

       N      N'th byte, character or field, counted from 1

       N-     from N'th byte, character or field, to end of line

       N-M    from N'th to M'th (included) byte, character or field

       -M     from first to M'th (included) byte, character or field
