## Name
|
|
|
|
rev - reverse lines
|
|
|
|
## Synopsis
|
|
|
|
```*sh
|
|
$ rev [files...]

```
|

|
## Description
|
|
|
|
`rev` reads the specified files line by line, and prints them to standard
|
|
output with each line being reversed characterwise. If no files are specified,
|
|
then `rev` will read from standard input.

## Examples
|
|
|
|
To print two files 'foo' and 'bar' in reverse:
|
|
```sh
|
|
$ cat foo bar
|
|
foo 1
|
|
foo 2
|
|
bar 1
|
|
bar 2
|
|
$ rev foo bar
|
|
1 oof
|
|
2 oof
|
|
1 rab
|
|
2 rab
|
|
```
|
|
|
|
To list files with their names in reverse:
|
|
```sh
|
|
$ ls
|
|
foo
|
|
bar
|
|
$ ls | rev
|
|
oof
|
|
rab
|
|
```
