| H A D | arith_yacc.c | diff 222386 Fri May 27 18:54:27 MDT 2011 jilles sh: Remove the "exp" builtin. The "exp" builtin is undocumented, non-standard and not very useful. If exp's return value is not used, something like VAR=$(exp EXPRESSION) is equivalent to VAR=$((EXPRESSION)) except that errors in the expression are fatal and quoting special characters is not needed in the latter case. If exp's return value is used, something like if exp EXPRESSION >/dev/null can be replaced by if [ $((EXPRESSION)) -ne 0 ] with similar differences. The exp-run showed that "let" is close enough to bash's and ksh's builtin that removing it would break a few ports. Therefore, "let" remains in 9.x. PR: bin/104432 Exp-run done by: pav (with some other sh(1) changes) |
