Hi, Tcl shell does not export changes to array variable env: http://wiki.tcl.tk/env
Test script: test_env_export1: --------- begin ---------- set env(FILENAME) filename_val puts $env(PATH) puts [exec /bin/bash -c {echo $PATH}] puts $env(FILENAME) puts [exec /bin/bash -c {echo $FILENAME}] --------- end ---------- Expect two lines of output "filename_val", receive only one. The bug affects 'guitool' feature of git-gui. cygwin 2.0.4-1 tclsh 8.5 Thanks, Stas. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
