EVAL(1CSH)              COMMAND REFERENCE              EVAL(1CSH)



NAME
     eval - evaluate and execute arguments (csh built-in)

SYNOPSIS
     eval [ arg... ]

DESCRIPTION
     The eval command causes the arguments to be read by the
     shell as input.  This is usually used to execute text
     generated by other commands or stored in variables.

EXAMPLES
     The following example shows a standard use of the utility
     tset(1), which gets the terminal type and can generate
     environment variable assignments.

          set noglob; eval `tset -s`; unset noglob

     In this use, the tset command might generate output like:

          set noglob ;
          setenv TERM aaa ;
          setenv TERMCAP <termcap string> ;
          unset noglob

     The eval command causes these commands to be run in the
     current shell, thus setting the TERM and TERMCAP variables.
     It should be noted that the extra ``set noglob'' in the
     example is required in order to prevent filename
     substitution in the tset output, and that the extra ``unset
     noglob'' in the example is recommended in case the tset
     command is aborted.

RETURN VALUE
     The value returned by eval is that of the commands executed.

CAVEATS
     A backquoted command that generates more than one word can
     not be executed by csh unless the eval command is used.
     This is used to inhibit usages like `*`, which generates an
     ambiguous command line.
