| 20 | .PP
|
|---|
| 21 | The $PATH shell variable controls the
|
|---|
| 22 | \s-1MINIX 3\s-1
|
|---|
| 23 | search rules.
|
|---|
| 24 | If a command \fIa.out\fR is given, the shell first tries to find an
|
|---|
| 25 | executable file in the working directory.
|
|---|
| 26 | If that fails, it looks in various system directories, such as
|
|---|
| 27 | \fI/bin\fR and \fI/usr/bin\fR.
|
|---|
| 28 | The\fR which\fR command makes the same search and gives the absolute
|
|---|
| 29 | path of the program that will be chosen, followed by other occurrences
|
|---|
| 30 | of the file name along the path.
