System call tracing tool for general Unix binaries.

This is a tool that comes with your operating system.  If it is not called strace, it may be called truss instead.  It is '''NOT''' written in Tcl - just a tool that often helps in tracking down problems.

[[RJ] - Actually, strace is in fact also a debugging command in TCL.  You can use the TCL [exec] to get the 
OS version of strace.]] - [RS]: Well, you can use any executable with [exec] that is on your $PATH...

See also: [ktrace]

[AMG]: A classmate of mine referred to [strace] as "the king of Unix commands."
