auto helpText = q"EOS Synopsis: tsv-select [options] [file...] tsv-select reads files or standard input and writes selected fields to standard output. Fields are written in the order listed. This is similar to Unix 'cut', but with the ability to reorder fields. Fields can be specified by field number or, for files with header lines, by field name. Use '--H|header' to enable selection by name. This also manages header lines from multiple files, retaining only the first header. Field numbers start with one. The field list is comma separated. Ranges can be used, and wildcards can be used when specifying fields by name. Fields can be dropped using '--e|exclude'. Fields not included in the '--f|fields' option can be selected as a group using '--r|rest'. Examples: # Selecting fields. Output is in the order listed tsv-select -H date,time file.tsv tsv-select -f 2,1 file.tsv tsv-select -f 5-7,2,9-11 tsv-select -H -f '*_date' file.tsv # Dropping fields tsv-select --exclude 1 file.tsv tsv-select -H -e date,time file.tsv # Move fields to the front or the back tsv-select -f 1 --rest first file.tsv # Move field 1 to the end tsv-select -H -f date --rest last # Move 'date' field to the front # Read multiple files, keep the header from only the first tsv-select data*.tsv -H --fields 1,2,4-7,14 Use '--help-verbose' for detailed information. Use '--help-fields' for details about field lists and field names. Options: EOS";
