Re: line numbers are false after (...) || {...}

[Emanuele Torre]

This has been fixed in bash5.1

    bash-5.1$ cat ~/tester
    #!/bin/bash

    ( echo foo; ) || {
      echo bar    # 4.line
      echo bar    # 5.line
      }           # 6.line
    echo lineno: $LINENO   # 7.line
    [[ -e bla]]     # 8.line
    bash-5.1$ ~/tester
    foo
    lineno: 7
    /home/emanuele6/tester: line 8: unexpected EOF while looking for `]]'
    /home/emanuele6/tester: line 9: syntax error: unexpected end of file
