Python escape special characters in password

First of all, using sshpass with the option -p means that you publish your password to anyone on the same machine. It's like putting your house key under your rug.

The error message comes from the shell which is being used to execute the command above (probably BASH). The character ! is interpreted as special character and means "look in the history for the text after me".

The problem is most likely inside of the sshpass script (since you didn't specify shell=True in Popen()). You can try to fix the script by making sure that it uses proper quoting and escaping.

The other solution is to pass env={'SSHPASS': 'test!@#'} to Popen() to set the environment for sshpass as explained in the manpage:

cmd = ['sshpass', '-e', 'ssh', '-o', 'UserKnownHostsFile=/dev/null', ...]
env = os.environ.copy()
env['SSHPASS'] = 'test!@#'
Popen(cmd, env=end)

Note: You should split the "-o key=value" into "-o", "key=value".

Escape Characters

To insert characters that are illegal in a string, use an escape character.

An escape character is a backslash \ followed by the character you want to insert.

An example of an illegal character is a double quote inside a string that is surrounded by double quotes:

Example

You will get an error if you use double quotes inside a string that is surrounded by double quotes:

txt = "We are the so-called "Vikings" from the north."

To fix this problem, use the escape character \":

How did you send the password to the HTTP request? My test password contains the "@", "#","!", etc. but I can manage to send the password to the RDP Auth Service by cover it with a double-quote (" ") like the following example:

python market_price_rdpgw_service_discovery.py --user machine-id --password "<The password with @, #, !, = , ...>" --clientid app_key
