Greetings, Moving from 5.3.2 on RedHat 3.0 to 5.6.2 on RedHat 4.0.
I’ve noticed that tcl now complains when exec-ing a PostScript-to-PDF file conversion utility in /usr/bin. A converted file does get created but tcl reports an error. Running the utility from the commandline shows no error. Both of the output PDFs are viewable but they differ in length by one byte.
This worked OK in 5.3.2 on RedHat 3.0
TIA for thoughts or solutions.

Binary files aaa.pdf and bbb.pdf differ

Your script is probably exiting with a non-zero result code. There are some TCL variables you can look at to see the cause of the exec failure. You can also check the exit status of your script when you run it outside of TCL.
Code:$ hcitcl
hcitcl>exec ./test.sh
Error: child process exited abnormally
hcitcl>echo $errorCode
CHILDSTATUS 16872 1
hcitcl>exit
$ ./test.sh
$ echo $?
1
