NAME

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

DESCRIPTION

       /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.
