proc_pid_exe(5) File Formats Manual proc_pid_exe(5)
/proc/pid/exe - symbolic link to program pathname
/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.
