Within a single bash session I am repeatedly re-running a command prefixed by sudo. Typically the password should be requested once and then cached. However, the present behavior is that the password is requested each time.
I opened another bash window and the same behavior is observed.
What may be causing that behavior?
User Shawn J Goff answered this particular quirk in another question that was the reverse of this one. The answer is here, and as follows:
From
man sudoers:timestamp_timeout
Number of minutes that can elapse before sudo will ask for a passwd again. The timeout may include a fractional component if minute granularity is insufficient, for example 2.5. The default is 5. Set this to 0 to always prompt for a password. If set to a value less than 0 the user's timestamp will never expire. This can be used to allow users to create or delete their own timestamps via sudo -v and sudo -k respectively.
I use the following command at the beginning of a session in bash on a Macintosh. It's great if I plan to use multiple commands that need sudoer access. All commands typed after this process will be executed as root.
sudo -s
Example:
Last login: Tue Jun 2 13:38:19 on ttys000
HostName:~ UserName$ sudo -s
Password:
bash-3.2# whoami
root
bash-3.2#
