foreach (tcsh command)

Loop, expand words, and execute commands

SYNTAX
       foreach name (wordlist)
       ...
       end     

Successively set the variable name to each member of wordlist and execute the sequence of commands between this command and the matching end.(Both foreach and end must appear alone on separate lines.)

The builtin command continue may be used to continue the loop prematurely and the builtin command break to terminate it prematurely.

When this command is read from the terminal, the loop is read once prompting with `foreach? ' (or prompt2) before any statements in the loop are executed. If you make a mistake typing in a loop at the terminal you can rub it out.

Examples

#! /bin/tcsh
# loop through a set of numbers
foreach myloop (1 2 3 4 5)
  echo -n "$myloop"
end


#! /bin/tcsh
# loop through a set of files
foreach f (*.html)
  echo $f
end


#! /bin/tcsh
# Rename a set of .csv file extensions to .xls
foreach f (*.csv)
  mv $f `basename $f .csv`.xls
end

`foreach' is a tcsh shell command.
