  35 $basename
  36     Export patron informations in CSV format.
  37     It prints to standard output. Use redirection to save CSV in a file.
  38
  39 Usage:
  40 $0 [--field=FIELD [--field=FIELD [...]]] [--separator=CHAR] [--show-header] [--where=CONDITION]
  41 $0 -h
  42
  43     -f, --field=FIELD       Field to export. It is repeatable and has to match
  44                             column names of the borrower table (also as 'description' and 'category_type'
  45                             If no field is specified, then all fields will be
  46                             exported.
  47     -s, --separator=CHAR    This character will be used to separate fields.
  48                             Some characters like | or ; will need to be escaped
  49                             in the parameter setting, like -s=\\| or -s=\\;
  50                             If no separator is specified, the delimiter pref
  51                             will be used (or a comma, if the pref is empty)
  52     -H, --show-header       Print field names on first row
  53     -w, --where=CONDITION   Condition to filter borrowers to export
  54                             (SQL where clause).
  55                             CONDITION must be enclosed by double quotes
  56                             You can use single quotes around a field value
  57                             within the condition like:
  58                                 --where "surname='De Lattre'"
  59     -h, --help              Show this help
