ferror - Man Page

print a stack trace when the given message is printed by the traced program


ferror [options] {program arg ...  | pid...}


ferror monitors the processes write system call for the specified MESSAGE, printing a stack trace of the process at the point of the write.

Stack Print Options

-number-of-frames count

Limit the back-trace to count frames. The default is to limit the back-trace to 10 frames. Specify 0 or "all" to print all frames.


Perform a light-weight stack backtrace containing only minimal information. Equivalent to -print -.


Perform a detailed stack back-trace that includes, where possible, inlined function calls, parameter names and values, and debug-names. Equivalent to -print inline,params,debug-names.

-print print-option,...

Specify the level of detail to include in a stack back-trace. print-option can be any of:

debug-names: use debug information, such as DWARF, to determine the name of functions

paths: include the full path to source files and libraries

inline: include in-line function in back-trace

locals: to include local variables from each frame

params: include the function parameters

To negate a print-option prefix it with "-".

Standard Frysk Options


The full path of the executable to read.


Do not attempt to read the corresponding executable when loading a core file.

-sysroot directory

The system root directory under which all executables, libraries, and source are located.

-debug class=level...

Set internal debug-tracing of the specified Java class to level (level can be NONE, INFO, WARNING, FINE, and FINEST). If the level is absent, FINE is assumed; if the class is absent, the global level is set.


ferror -e "No such file or directory" -- ls fake
