Hi,
When working in vi, the CTRL+j command for merging lines is very convenient. Is there an equivalent for splitting them (inserting a line break)? I often find myself pressing "i" + "return" + "esc", which I find a bit lengthy.
Thanks in advance! (3 Replies)

chmod
CHMOD(1) General Commands Manual CHMOD(1)NAME
chmod - change mode
SYNOPSIS
chmod mode file ...
DESCRIPTION
The mode of each named file is changed according to mode, which may be an octal number or a symbolic change to the existing mode. A mode
is an octal number constructed from the OR of the following modes.
0400 read by owner
0200 write by owner
0100 execute (search in directory) by owner
0070 read, write, execute (search) by group
0007 read, write, execute (search) by others
A symbolic mode has the form:
[who] op permission
The who part is a combination of the letters u (for user's permissions), g (group) and o (other). The letter a stands for ugo. If who is
omitted, the default is a.
Op can be + to add permission to the file's mode, - to take away permission, and = to assign permission absolutely (all other bits will be
reset).
Permission is any combination of the letters r (read), w (write), x (execute), a (append only), and l (exclusive access).
Only the owner of a file or the group leader of its group may change the file's mode.
