examination  of  process run

• display the calls to open

examination of a running process

• find the processes which are using a directory (for example, in case on a failed umount because the mount point is busy )

• LD_LIBRARY_PATH specifies (comma separated) directories to be searched before the default directories
 
• LD_NOVERSION forces the linker to ignore executable and shared object versions
 
• LD_BIND_NOW forces the linker to bind all shared objects during process initialisation
 
• LD_PRELOAD specifies (space separated) shared objects to be linked after the program is executed but before any other shared objects referenced by the program
 
• LD_PROFILE defines a shared object to be profiled (i.e. generation a gmon.out file to be read with gprof)
LD_PROFILE_OUTPUT defines an alternative logfile name
 
• LD_AUDIT defines a (colon separated) list of shared objects used to audit the linkage
 
• LD_BREADTH requires the initialization routines to be called in reverse load order.
 
• LD_DEBUG=help to get the usage description
LD_DEBUG=bindings returns the bound shared objects
LD_DEBUG=bindings,detail also returns real and relative relocations addresses
LD_DEBUG=libs traces the share object lookup (same data as ldd)
LD_DEBUG=symbols traces the symbols lookup
LD_DEBUG_OUTPUT defines a file to log debug data
