auto helpTextVerbose = 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. Fields can be repeated and ranges can be used. Wildcards can be used when specifying fields by name, and escapes can be used to specify fields names containing special characters. Run '--help-fields' for details. Fields can be excluded using '--e|exclude'. All fields not excluded are output. Fields not included in the '--f|fields' option can be selected as a group using '--r|rest'. '--f|fields' and '--r|rest' can be used with '--e|exclude' to reorder non-excluded fields. Examples: # Keep the first field from two files tsv-select -f 1 file1.tsv file2.tsv # Keep fields 1 and 2, retaining the header from only the first file tsv-select -H -f 1,2 file1.tsv file2.tsv # Keep the 'time' field tsv-select -H -f time file1.tsv # Keep all fields ending '_date' or '_time' tsv-select -H -f '*_date,*_time' file.tsv # Drop all the '*_time' fields tsv-select -H --exclude '*_time' file.tsv # Field reordering and field ranges tsv-select -f 3,2,1 file.tsv tsv-select -f 1,4-7,11 file.tsv tsv-select -f 1,7-4,11 file.tsv # Repeating fields tsv-select -f 1,2,1 file.tsv tsv-select -f 1-3,3-1 file.tsv # Move fields to the front tsv-select -f 5 --rest last file.tsv tsv-select -H -f Date,Time --rest last file.tsv # Move fields to the end tsv-select -f 4,5 --rest first file.tsv tsv-select -f '*_time' --rest first file.tsv # Move field 2 to the front and drop fields 10-15 tsv-select -f 2 -e 10-15 file.tsv # Move field 2 to the end, dropping fields 10-15 tsv-select -f 2 -rest first -e 10-15 file.tsv Use '--help-fields' for detailed help on field lists. Notes: * One of '--f|fields' or '--e|exclude' is required. * Fields specified by '--f|fields' and '--e|exclude' cannot overlap. * When '--f|fields' and '--e|exclude' are used together, the effect is to specify '--rest last'. This can be overridden by using '--rest first'. * Each input line must be long enough to contain all fields specified with '--f|fields'. This is not necessary for '--e|exclude' fields. * Specifying names of fields containing special characters may require escaping the special characters. See '--help-fields' for details.
