- Convert tabs in each file to spaces, writing to standard output:
2022-12-04 09:12:49 +00:00
`expand {{path/to/file}}`
2016-06-21 18:38:36 +01:00
- Convert tabs to spaces, reading from standard input:
`expand`
- Do not convert tabs after non blanks:
2022-12-04 09:12:49 +00:00
`expand -i {{path/to/file}}`
2016-06-21 18:38:36 +01:00
- Have tabs a certain number of characters apart, not 8:
2022-12-04 09:12:49 +00:00
`expand -t={{number}} {{path/to/file}}`
2016-06-21 18:38:36 +01:00
- Use a comma separated list of explicit tab positions:
2016-06-21 18:38:36 +01:00
`expand -t={{1,4,6}}`
