Specifying the Field Delimiter
The default delimiter between fields is a comma (,). You can override this using the -delimiter option. If the delimiter is a character that is difficult to specify on the command line, specify the delimiter in an options file instead. For details, see Options File Syntax.
For example, the Linux bash shell parser makes it difficult to specify a tab delimiter on the command line, so you can put the options in a file instead. In the example options file below, the string literal after -delimiter should contain a tab character.
$ cat delim.opt
-input_file_type
delimited_text
-delimiter
"tab"
$ mlcp.sh import ... -mode local -input_file_path /space/mlcp/data \
-options_file delim.opt
