cat /proc/<pid>/environ If you want to have pid(s) of a given running executable you can, among a number of other possibilities, use pidof: AlberT$ pidof sshd 30690 6512 EDIT: I totally quote Dennis Williamson and Teddy comments to achieve a more readable output.

Dig will also do it quite nicely: dig -t txt example.com and if you add the +short option you get just the txt record in quote marks with no other cruft.
Many people seem to be afraid of mixing stable with testing, but frankly, testing is fairly stable in its own right, and with proper preferences and solution checking, you can avoid the “stability drift” that puts your core packages on the unstable path. “Testing is fairly stable??”, you ask. Yes. In order for a package … Read more
There isn’t a great deal of difference between the two; 127/8 (eg: 127.0.0.0 => 127.255.255.255) are all bound to the loopback interface.

First of all a minor terminology nitpick: chmod doesn’t remove permissions. It CHANGES them. Now the meat of the issue — The mode 777 means “Anyone can read, write or execute this file” – You have given permission for anyone to do (effectively) whatever the heck they want. Now, why is this bad? You’ve just … Read more
You can check if a process listens on a TCP or UDP port with netstat -tuplen. To check whether some ports are accessible from the outside (this is probably what you want) you can use a port scanner like Nmap from another system. Running Nmap on the same host you want to check is quite … Read more
If you’re using Bash, you can run disown -h job disown disown [-ar] [-h] [jobspec …] Without options, each jobspec is removed from the table of active jobs. If the -h option is given, the job is not removed from the table, but is marked so that SIGHUP is not sent to the job if … Read more
No, there isn’t (I just checked 1 hour ago). You can comment the bind-address in my.cnf: Note: « 1 hour ago » is now more than 10 years ago. #skip-networking #bind-address = 127.0.0.1 If you want only 2 IPs, you will then have to use a firewall. For MySql version 8.0.13 and above, you can … Read more
