FileHandle
Provides object methods for working with filehandles. Provides the following methods:
The following additional FileHandle methods act as front-ends for the corresponding built-in Perl functions (see the Anonymous tutorial Perl Developing or the perlfunc manpage for more detail):
clearerr
| getc
|
close
| gets
|
eof
| seek
|
fileno
| tell |
The next group of FileHandle methods correspond to Perl special variables (see Perl Developing or the perlvar manpage):
autoflush
| format_page_number
|
format_formfeed
| format_top_name
|
format_line_break_characters
| input_line_number
|
format_lines_left
| input_record_separator
|
format_lines_per_page
| output_field_separator
|
format_name
| output_record_separator |
Finally, the following methods are useful:
- $fh
->print - See Perl's built-in
printfunction. - $fh
->printf - See Perl's built-in
printffunction. - $fh
->getline - Works like Perl's <FILEHANDLE> construct, except that it can be safely called in an array context (but it still returns just one line).
- $fh
->getlines - Works like Perl's <FILEHANDLE> construct when called in an array context to read all remaining lines in a file.
