It is a really weird problem, but on new systems(Fedora, Ubuntu) ctrl+c has no effect for certain tools:
if I execute yum list which runs for almost a minute I can't interrupt to run with ctrl+c
$time yum list >/dev/null ^C^C^C^C^C^C^C^C^C
The command execution won't stop.
However to interrupt find is possible.
$ time find / >/dev/null 2>&1 ^C real 0m0.741s user 0m0.033s sys 0m0.124s
I am curious what is causing this.
I have to following settings:
$ stty -a speed 38400 baud; rows 36; columns 158; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 -hupcl -cstopb cread -clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc -ixany -imaxbel -iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke
I couldn't find the description of the problem yet, I appreciate if somebody would be that kind to shed some light.
Thanks in advance.
