Hello dear readers! Welcome back to another section of my Tutorial on Python. In this tutorial guide, we are going to be studying about the Os pathconf() method.
The Python os pathconf() method returns the system configuration information relevant to a named file.
The Python os pathconf() method returns the system configuration information relevant to a named file.
Syntax
Below is the syntax for Python Os pathconf() method -
os.pathconf(path, name);
RECOMMENDED POST: Python os.fpathconf() Method with example
Parameter Details
- path - This is the file path.
- name - This specifies the config value to retrieve; it may be a string, which is the name of a defined system value; these names are been specified in a number of standards (POSIX.1, Unix 95, Unix 98).
Return Value
This returns system configuration information of a file.
Example
The following below is a simple example -
#!/usr/bin/python
import os, sys
print "%s" % os.pathconf_names
# Retrieve Maximum Length of a filename
no = os.pathconf('a2.py', 'PC_NAME_MAX')
print "Maximum length of a filename :%d" % no
# Retrieve file size
no = os.pathconf('a2.py', 'PC_FILESIZEBITS')
print "file size in bits :%d" % no
Output
When the above code is executed, it will produce the following result -
{'PC_MAX_INPUT': 2, 'PC_VDISABLE': 8, 'PC_SYNC_IO': 9,
'PC_SOCK_MAXBUF': 12, 'PC_NAME_MAX': 3, 'PC_MAX_CANON': 1,
'PC_PRIO_IO': 11, 'PC_CHOWN_RESTRICTED': 6, 'PC_ASYNC_IO': 10,
'PC_NO_TRUNC': 7, 'PC_FILESIZEBITS': 13, 'PC_LINK_MAX': 0,
'PC_PIPE_BUF': 5, 'PC_PATH_MAX': 4}
Maximum length of a filename :255
file size in bits : 64RECOMMENDED POST: Python os.openpty() Method with example
Alright guys! This is where we are rounding up for this tutorial post. In my next tutorial, we are going to be discussing about the Python OS pipe() Method.
