Linux joe command
Linux Command EncyclopediaThe Linux joe command is used to edit text files.
Joe is a powerful full-screen text editing program. Its operation complexity is slightly higher than Pico, but it has relatively complete features. Joe can open multiple files at once, with each file placed in a separate editing area, and can perform cut-and-paste actions between files.

joe main.c

I A main.c (c) Row 1 Col 1 12:28 Ctrl-K H for help

#include <linux/sysctl.h>
#include <linux/nsproxy.h>
static struct list_head *
net_ctl_header_lookup(struct ctl_table_root *root, struct nsproxy *namespaces)
{
return &namespaces->net_ns->sysctl_table_headers;
}
static struct ctl_table_root net_sysctl_root = {
.lookup = net_ctl_header_lookup,
};
static int sysctl_net_init(struct net *net)
