.B basename /user/ast/file.c
# Strips path to yield \fIfile.c\fP
.TP 20
.B basename /user/file.c .c
# Strips path and \fI.c\fP to yield \fIfile\fP
.TP 20
.B dirname /user/file.c
# Strips basename to yield \fI/user\fP
.SH DESCRIPTION
.PP
.I Basename
removes the initial directory names (if any) yielding the name of the
file itself.
If a second argument is present, it is interpreted as a suffix and is
also stripped, if present.
.PP
