Removing sudo password is typically not a good practice. If you’re a seasoned system administrator, or you’re the only one using your own desktop, being prompted for a sudo password can get really annoying. Here’s how to stop getting prompted every time you run sudo.
Run visudo.
sudo visudo |
sudo visudo
Edit the sudo line and set to below.
%sudo ALL=(ALL) NOPASSWD: ALL |
%sudo ALL=(ALL) NOPASSWD: ALL
Save file.
Here’s the command to remove quotes from a string in Bash by using the tr -d command. I’m using jq tool to extract the access key from a json file. Bash returns a string surrounded by quotes. To remove the quotes, just pipe the string to the tr -d command.
jq .AccessKey.AccessKeyId key.json |
jq .AccessKey.AccessKeyId key.json
Result:
"ASDFSDFSDFASDFSDFSDFGHGDF" |
"ASDFSDFSDFASDFSDFSDFGHGDF"
Using tr -d.
jq .AccessKey.AccessKeyId key.json | tr -d \" |
jq .AccessKey.AccessKeyId key.json | tr -d \"
Result:
ASDFSDFSDFASDFSDFSDFGHGDF |
ASDFSDFSDFASDFSDFSDFGHGDF
