TCL : Regarding init.tcl file in TCL

Can anyone explain me what is the use of init.tcl?

When actually it is loaded by the TCL interpreter?

The description for this file is shown as

startup file for TCL .

But According to my knowledge .tclshrc is the start up file.

Can anyone explain this?

Actually, init.tcl is the first file that is loaded by a Tcl_Interp*. Its job is to setup the different package loading mechanisms.

Some programs, most notably tclsh, will source the .tclshrc. This is usually done using Tcl_SourceRCFile.

So init.tcl is sourced for every Tcl interpreter, while the .tclshrc is only sourced by some programs that explicitly do that.

* does not apply to safe interpreters
