|-e||Causes all conventional output from command to be redirected to the standard error as diagnostic output.|
|-f file||Causes all diagnostic output from command to be redirected to file, which is created if it does not exist. If it already exists, all diagnostic output is appended to the end of file.|
|--||Causes fd2 to stop further option processing, forcing it to treat all following arguments as command [arg ...] .|
If fd2 detects an error, it prints an appropriate diagnostic and exits with a non-zero status. Otherwise, the exit status is that of the executed command.
EXECSHELL If set to a non-empty string, the value of this variable is taken as the path name of the shell which is invoked to execute the specified command when it does not begin with the proper magic number or a #!shell sequence. PATH If set to a non-empty string, the value of this variable is taken as the sequence of directories which is used to search for the specified command.
The examples below which refer to /tmp/$$ assume that this directory exists and is writable by the user. The following command line:
fd2 -e echo progname: Error message
causes all conventional output from echo to be redirected to the standard error as diagnostic output. The following command line:
fd2 make foo >/tmp/$$/foo.outerr
causes all conventional and diagnostic output from make to be redirected to the file /tmp/$$/foo.outerr, which is first created by the shell. In contrast:
fd2 -f /tmp/$$/foo.err make foo >/tmp/$$/foo.out
causes all conventional output to be redirected to the file /tmp/$$/foo.out, which is created by the shell. All diagnostic output is redirected to the file /tmp/$$/foo.err, which is created by fd2 if it does not already exist.
