| 22 | $Usage
|
|---|
| 23 | $name searches each directory specified in the PATH environment variable
|
|---|
| 24 | for executable files that match the specified patterns. Patterns are
|
|---|
| 25 | given as Korn shell filename patterns. They are surrounded by implicit
|
|---|
| 26 | '*' characters, so that \"foo\" will match any executble file whose name
|
|---|
| 27 | contains contains \"foo\". This can be overridden by using '^' and '$' to
|
|---|
| 28 | force a match to start at the beginning and end at the end of a filename
|
|---|
| 29 | respectively. Characters that are special to the shell must generally
|
|---|
| 30 | be protected from the shell by surrounding them with quotes.
|
|---|
| 31 | Examples:
|
|---|
| 32 | $name foo
|
|---|
| 33 | lists all executable files in PATH that contain foo.
|
|---|
| 34 | $name '^b*sh$'
|
|---|
| 35 | lists all executable files in PATH that start with b and end with sh.
