“Max open files” for working process

Question

Is it possible to increase \"Max open files\" parameter for working process ? I mean this parameter:

cat /proc//limits | grep files

Answer 1

Another option is to use the prlimit command (from the util-linux package). For example if you want to set the maximum number of open files for a running process to 4096:

prlimit -n4096 -p pid_of_process
