chdir
EXPR
This function changes the working directory to
EXPR
,
if possible.
If
EXPR
is omitted, it changes to the home directory.
The function returns 1 upon success, 0 otherwise (and puts the error
code into
$!
).
chdir "$prefix/lib" or die "Can't cd to $prefix/lib: $!\n";
The following code can be used to move to the user's home directory, one way or another:
$ok = chdir($ENV{"HOME"} || $ENV{"LOGDIR"} || (getpwuid($<))[7]);
Alternately, taking advantage of the default, you could say this:
$ok = chdir() || chdir((getpwuid($<))[7]);
See also the Cwd module, described in Chapter 7, The Standard Perl Library , which lets you keep track of your current directory.
