Runs a program or operating system command, and waits for it to exit before continuing the translation.
Parameters
Command Line
To run a program, the command-line parameter must start with the name of a program (.exe on Windows or an executable on Linux/Mac) or batch file (.bat) that is either fully specified or is in the PATH. It can contain additional arguments as well, which are passed as command-line arguments to the program or batch script.
To run multiple operating system commands, use && to delimit commands. For example:
cd c:\temp && dir *.* && pause
cd /Users && ls -l
If paths contain spaces, enclose the path in double quotes, and only on Windows enclose the entire command in double quotes. For example:
""C:\run me\something.exe" -filepath "C:\path here\filename.txt""
/usr/bin/head -n "/path/to/some file.txt"
Exit Code Attribute
If an Exit Code Attribute is specified, it will be set to the executed program's exit code: usually 0 for success and nonzero for failure.
