I have found the signal processing behavior on my Solaris 10 is changed. For example, when I Ctrl+C, the program can't exit. Use psig to check the signal processing behavior:  HUP     defaultINT     ignoredQUIT    ignoredILL     defaultI can see the INT signal is changed to ignored. I want to restore the default behavior, How can I do it? Thanks very much in advance!
How to restore the default signal processing behavior on Solaris?
