tcsh returns a wrong value as $status
Issue
- The $status value of tcsh must be exit status of the last command.
- However, there is the case that the $status value of tcsh is not exit status of the last command.
- Step to reproduce:
Case 1) ----- # cat no-exist | wc -l cat: no-exist: No such file or directory 0 # echo $status 1 <= Expected status is 0. ----- 1st: cat no-exist => exit status 1 2nd: wc -l => exit status 0 $status must be 0 Case 2) ----- # echo `cat no-exist | wc -l` cat: no-exist: No such file or directory 0 # echo $status 1 <= Expected status is 0. ----- 1st: cat no-exist => exit status 1 2nd: wc -l => exit status 0 3rd: echo => exit status 0 $status must be 0
