| 20 | .SH DESCRIPTION |
|---|
| 21 | .PP |
|---|
| 22 | Returns the absolute path name of the current working directory. |
|---|
| 23 | .SH EXAMPLE |
|---|
| 24 | Sometimes it is useful to change to a known directory when running |
|---|
| 25 | some external command using \fBexec\fR, but it is important to keep |
|---|
| 26 | the application usually running in the directory that it was started |
|---|
| 27 | in (unless the user specifies otherwise) since that minimizes user |
|---|
| 28 | confusion. The way to do this is to save the current directory while |
|---|
| 29 | the external command is being run: |
|---|
| 30 | .CS |
|---|
| 31 | set tarFile [file normalize somefile.tar] |
|---|
| 32 | set savedDir [\fBpwd\fR] |
|---|
| 33 | cd /tmp |
|---|
| 34 | exec tar -xf $tarFile |
|---|
| 35 | cd $savedDir |
