z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

fc
the one indicated by first through to the previous command entered. If you
omit both first and last with this option, the default command range is the
16 most recently entered commands.
–n Suppresses command numbers when displaying commands.
–r Reverses the order of the commands in the command range.
–s Reenters exactly one command without going through an editor. If a
command specifier is given, fc selects the command to reenter as
described earlier; otherwise, fc uses the last command entered. To perform
a simple substitution on the command before reentry, use a parameter of
the form old=new. The string new replaces the first occurrence of string old.
fc displays the (possibly modified) command before reentering it.
