On Linux, the symlink /proc/<pid>/exe has the path of the executable. Use the command readlink -f /proc/<pid>/exe to get the value. On AIX, this file does not exist. You could compare cksum <actual path to binary> and cksum /proc/<pid>/object/a.out.
I used /etc/crontab. I used vi and entered in the PATHs I needed into this file and ran it as root. The normal crontab overwrites PATHs that you have set up. A good tutorial on how to do this. The systemwide cron file looks like this: This has the username field, as used by /etc/crontab. …
The express.static middleware is separate from res.sendFile, so initializing it with an absolute path to your public directory won’t do anything to res.sendFile. You need to use an absolute path directly with res.sendFile. There are two simple ways to do it: res.sendFile(path.join(__dirname, ‘../public’, ‘index1.html’)); res.sendFile(‘index1.html’, { root: path.join(__dirname, ‘../public’) }); Note: __dirname returns the directory …

To summarize: On Unixes with /proc really straight and realiable way is to: readlink(“/proc/self/exe”, buf, bufsize) (Linux) readlink(“/proc/curproc/file”, buf, bufsize) (FreeBSD) readlink(“/proc/self/path/a.out”, buf, bufsize) (Solaris) On Unixes without /proc (i.e. if above fails): If argv[0] starts with “https://stackoverflow.com/” (absolute path) this is the path. Otherwise if argv[0] contains “https://stackoverflow.com/” (relative path) append it to cwd …
