+.SH NAME
+/proc/pid/exe \- symbolic link to program pathname
+.SH DESCRIPTION
+.TP
+.IR /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
+.IR /proc/ pid /exe
+to run another copy of the same executable that is being run by
+process
+.IR pid .
+If the pathname has been unlinked, the symbolic link will contain the
+string \[aq]\ (deleted)\[aq] appended to the original pathname.
+.\" The following was still true as at kernel 2.6.13
+In a multithreaded process, the contents of this symbolic link
+are not available if the main thread has already terminated
+(typically by calling
+.BR pthread_exit (3)).
+.IP
+Permission to dereference or read
+.RB ( readlink (2))
+this symbolic link is governed by a ptrace access mode
+.B PTRACE_MODE_READ_FSCREDS
+check; see
+.BR ptrace (2).
+.IP
+Under Linux 2.0 and earlier,
+.IR /proc/ pid /exe
+is a pointer to the binary which was executed,
+and appears as a symbolic link.
+A
+.BR readlink (2)
+call on this file under Linux 2.0 returns a string in the format:
+.IP
+.in +4n
+.EX
+[device]:inode
+.EE
+.in
+.IP
+For example, [0301]:1502 would be inode 1502 on device major 03 (IDE,
+MFM, etc. drives) minor 01 (first partition on the first drive).
+.IP
+.BR find (1)
+with the
+.I \-inum
+option can be used to locate the file.
