что означает «только для внутреннего -» в команде mount и почему бы вам не вызвать файловую систему /sbin/mount?

Мое решение — использовать больше ключей:

set $ws0 "0:`:www"
set $ws1 "1:1"
set $ws2 "2:2"
set $ws3 "3:3:fm"
set $ws4 "4:4"
set $ws5 "5:5"
set $ws6 "6:6:dev"
set $ws7 "7:7"
set $ws8 "8:8"
set $ws9 "9:9"
set $ws10 "10:0:music"
set $ws11 "11:-:jd"
set $ws12 "12:=:comm"
set $ws13 "13:B"
set $ws14 "14:H"
set $ws15 "15:E"
set $ws16 "16:I"
set $ws17 "17:D:upwork"
