: What does the command shift <number> ??
: There is no man page. It looks to me that it is something from bash, but I
: don't know what.
here's my man page :
shift - shell built-in function to traverse either a shell's
argument list or a list of field-separated words
shift [ n ]
shift [ variable ]
shift [ n ]
The positional parameters from $n+1 ... are renamed $1
... . If n is not given, it is assumed to be 1.
The components of argv, or variable, if supplied, are
shifted to the left, discarding the first component. It is
an error for the variable not to be set or to have a null
The positional parameters from $n+1 $n+1 ... are renamed $1
..., default n is 1. The parameter n can be any arithmetic
expression that evaluates to a non-negative number less than
or equal to $#.
On this man page, ksh(1) commands that are preceded by one
or two * (asterisks) are treated specially in the following
1. Variable assignment lists preceding the command remain
in effect when the command completes.
2. I/O redirections are processed after variable assign-
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in
the format of a variable assignment, are expanded with
the same rules as a variable assignment. This means
that tilde substitution is performed after the = sign
and word splitting and file name generation are not
csh(1), ksh(1), sh(1)
Couldn't have been clearer
