How to use password with special character in mount command linux ?

I faced a problem while using mount command with a password containing special characters. The error that I got was “permission denied”. On analyzing the root cause, I figured out that because of the special character, the authentication failed.

The syntax of the mount command is given below.

> mount -t cifs -o username= ,password=[password] [windows-share-dir-path] [dir-in-linux]

Here my password was something like below. It has so many special characters.

> i2_Gw$wF?Xs4zq??K


The solution is simple. Create a text file and enter the credentials into that file.

I have created a file with the name credentials.ini


Now save this file and use this credentials file in the mount command. The syntax is given below.

mount -t cifs -o credentials=credentials.ini [windows-share-dir-path] [dir-in-linux]


Now execute this command and your problem will be solved. !!!!

How to convert or change the data type of columns in Pandas dataframe ?

Changing the datatype of columns in pandas dataframe is very easy. Here I am using stype() function to perform the typecase operation.  Refer to the following example. The type conversion is happening in the line number 10 of the code.


You can add as many columns as you want to convert the data type or typecast. For example if you want to typecast the columns emp_id and salary, use the following syntax.

> df = df.astype({‘salary’:‘int’, ’emp_id’:’int’})
