Ahoy,
how to get the following idiom ash-like translated? (I just called busybox on
my raspbian buster)
echo '12 34' | read a b ; echo "'${a}''${b}'"
''''
Doesnt the manual state that "The read utility shall read a single logical
line from standard input into one or more shell variables."
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html
IFS
Determine the internal field separators used to delimit fields; see Shell
Variables.
And
The shell shall set IFS to <space> <tab> <newline> when it is invoked.
And why/how?
# echo $IFS|xxd
00000000: 0a .
# unset IFS; echo $IFS|xxd
00000000: 0a .
# IFS=" "; echo $IFS|xxd
00000000: 0a .
# IFS=" " echo $IFS|xxd
00000000: 0a .
e.g. in zsh:
IFS=' ' ; echo $IFS|xxd
00000000: 200a
