I have a relative path
$base_path = "input/myMock.TGZ";
myMock.TGZ
is the file name located in input folder.
The filename can change. But the path is always stored in $base_path
.
I need to check if the file exists in $base_path
.

You might want a variant of exists ... perldoc -f "-f"
-X FILEHANDLE
-X EXPR
-X DIRHANDLE
-X A file test, where X is one of the letters listed below. This unary operator takes one argument,
either a filename, a filehandle, or a dirhandle, and tests the associated file to see if something is
true about it. If the argument is omitted, tests $_, except for "-t", which tests STDIN. Unless
otherwise documented, it returns 1 for true and '' for false, or the undefined value if the file
doesn’t exist. Despite the funny names, precedence is the same as any other named unary operator.
The operator may be any of:
-r File is readable by effective uid/gid.
-w File is writable by effective uid/gid.
-x File is executable by effective uid/gid.
-o File is owned by effective uid.
-R File is readable by real uid/gid.
-W File is writable by real uid/gid.
-X File is executable by real uid/gid.
-O File is owned by real uid.
-e File exists.
-z File has zero size (is empty).
-s File has nonzero size (returns size in bytes).
-f File is a plain file.
-d File is a directory.
-l File is a symbolic link.
-p File is a named pipe (FIFO), or Filehandle is a pipe.
-S File is a socket.
-b File is a block special file.
-c File is a character special file.
-t Filehandle is opened to a tty.
-u File has setuid bit set.
-g File has setgid bit set.
-k File has sticky bit set.
-T File is an ASCII text file (heuristic guess).
-B File is a "binary" file (opposite of -T).
-M Script start time minus file modification time, in days.
#!/usr/bin/perl -w
$fileToLocate = '/whatever/path/for/file/you/are/searching/MyFile.txt';
if (-e $fileToLocate) {
print "File is present";
}
if (-e $base_path)
{
# code
}
-e
is the 'existence' operator in Perl.
You can check permissions and other attributes using the code on this page.
Use:
if (-f $filePath)
{
# code
}
-e
returns true even if the file is a directory. -f
will only return true if it's an actual file
Use the below code. Here -f checks, it's a file or not:
print "File $base_path is exists!\n" if -f $base_path;
and enjoy
You can use: if(-e $base_path)
if(-e $base_path){print "Something";}
would do the trick
