Hello everyone,
When I try to print a single non-control character to the terminal, I
get nothing back. I tried different terminals and shells; it happens
everywhere, only with Fish.
echo -n x # prints nothing
printf "%d" 9 # idem
printf "%s" Y # idem
printf "%x" 15 # idem
echo x # prints "x\n"
printf "%s" Yep # prints "Yep"
printf "%02x" 15 # prints "0f"
printf "%d" 10 # prints "10"
printf "%x" 16 # idem
echo # prints "\n"
printf \n # idem
printf \a # plays sound
This problem affects any program run under Fish which prints to
stdin/stderr, e.g.:
printf 'int main() { printf("x"); }' \
| cc -x c -w - -o test-prog \
; ./test-prog
Since, however, printing to other files, pipes, etc. seems to work,
the issue must concern echoing.
echo (echo -n x) # prints "x\n"
printf "%s\n" (printf x) # idem
printf x\n | cat > test-file; cat test-file # idem
Can anyone reproduce with Fish 2.5.0?
Giuseppe
