NAME         top

       /proc/pid/exe - symbolic link to program pathname

DESCRIPTION         top

       /proc/pid/exe
              Under Linux 2.2 and later, this file is a symbolic link
              containing the actual pathname of the executed command.
              This symbolic link can be dereferenced normally;
              attempting to open it will open the executable.  You can
              even type /proc/pid/exe to run another copy of the same
              executable that is being run by process pid.  If the
              pathname has been unlinked, the symbolic link will contain
              the string ' (deleted)' appended to the original pathname.
              In a multithreaded process, the contents of this symbolic
              link are not available if the main thread has already
              terminated (typically by calling pthread_exit(3)).

              Permission to dereference or read (readlink(2)) this
              symbolic link is governed by a ptrace access mode
              PTRACE_MODE_READ_FSCREDS check; see ptrace(2).

              Under Linux 2.0 and earlier, /proc/pid/exe is a pointer to
              the binary which was executed, and appears as a symbolic
              link.  A readlink(2) call on this file under Linux 2.0
              returns a string in the format:

                  [device]:inode

              For example, [0301]:1502 would be inode 1502 on device
              major 03 (IDE, MFM, etc. drives) minor 01 (first partition
              on the first drive).

              find(1) with the -inum option can be used to locate the
              file.
