tcsh built-in command descriptions
@ (at) built-in command for tcsh: Print the value of tcsh shell variables
Format
@
@ name = expr
@ name[index] = expr
@ name+ + |– –
@ name[index]+ + |– –
Description
@ (at) in the tcsh shell prints the value of tcsh shell variables.
Options
@ in the tcsh shell supports the following options:
name = expr
Assigns the value of expr to name.
name[index] = expr
Assigns the value of expr to the index’th component of name. Both name
and its index’th component must already exist.
For both name = expr and name[index] = expr , expr may contain the
operators *, +, etc. as in C. If expr contains , &, or ″ then at least part
of expr must be placed within (). The syntax of expr has nothing to do with
that described under “Expressions” on page 647.
expr must evaluate to a numeric expression. Therefore, use set instead of
@ to assign array variables.
name+ + |– –
Increments (++) or decrements (– –) name.
name[index]+ + |– –
Increments (++) or decrements (– –) name’s index’th component.
Usage notes
1. The space between @ and name is required.
2. The spaces between name and = and between = and expr are optional.
3. Components of expr must be separated by spaces.
