Perl was originally developed for the text processing like extracting the required information from a specified text file and for converting the text file into a different form. These operations can be performed by the use of various inbuilt file functions.
Following are some of the useful functions in Perl to work on Files:
|glob()||Used to print the files present in a directory passed to it as an argument|
|tell()||Used to get the position of the read pointer in a File with the use of its FileHandle|
|getc()||Used to read the next character from the file whose File Handle is passed to it as argument|
|reverse()||Returns the List in reverse order when used in List context and returns a concatenated string of the values of the List, with each character of the string in the opposite order when used in scalar context|
|rename()||Renames the old name of a file to a new name as given by the user|
