For each pair of input lines with identical join fields, write a
line to standard output. The default join field is the first, delimited by
blanks.
When FILE1 or FILE2 (not both) is -, read standard input.
- -a
<FILENUM>
- also print unpairable lines from file FILENUM, where FILENUM is 1 or 2,
corresponding to FILE1 or FILE2
[possible values: 1, 2]
- -v
<FILENUM>
- like -a FILENUM, but suppress joined output lines
[possible values: 1, 2]
- -e
<EMPTY>
- replace missing input fields with EMPTY
- -i,
--ignore-case
- ignore differences in case when comparing fields
- -j
<FIELD>
- equivalent to '-1 FIELD -2 FIELD'
- -o
<FORMAT>
- obey FORMAT while constructing output line
- -t
<CHAR>
- use CHAR as input and output field separator
- -1 <FIELD>
- join on this FIELD of file 1
- -2 <FIELD>
- join on this FIELD of file 2
- --check-order
- check that the input is correctly sorted, even if all input lines are
pairable
- --nocheck-order
- do not check that the input is correctly sorted
- treat the first line in each file as field headers, print them without
trying to pair them
- -z,
--zero-terminated
- line delimiter is NUL, not newline
- -h, --help
- Print help
- -V, --version
- Print version
