Full Discussion: Cut command with dynamic passing of delimiter and position values
Top Forums Shell Programming and Scripting Cut command with dynamic passing of delimiter and position values Post 303023045 by apmcd47 on Tuesday 11th of September 2018 05:46:04 AM

If I read you correctly you wish to dynamically change the delimiter used by cut:
Code:
DELIM=,
echo "a,b,c,d,e" | cut -d "$DELIM" -f 3
DELIM="|"
echo "A|B|C|D|E" | cut -d "$DELIM" -f 2

Or is it a case you don't know whether the delimiter will be comma, a pipe or something else?
Code:
echo "A|B|C|D|E" | tr '|;' ',,' | cut -d "," -f 2
echo "a;b;c;d;e" | awk -F"[,|;]" '{print $3}'

All the above are simplistic examples.

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
