Puppy Linux Discussion Forum

Hello.

When writing a script in ScPup64 it happend to me that the read command ignores the linefeed in $IFS.
Script and discussion about it can be found here: viewtopic.php?p=15689#p15689

I have repeated the very trivial test in the recent ScPup64-21.01:

# set | grep IFS
IFS=$' \t\n'
# read A B <<<`echo -e "eins zwei"`
# echo $A $B
eins zwei
# read A B <<<`echo -e "eins\nzwei"`
# echo $A $B
eins
# echo -e "eins\nzwei"
eins
zwei
# read -d "\n" A B <<<`echo -e "eins\nzwei"`
# echo $A $B
eins zwei
# 

bash versions are:

• ScPup64-20.06+2-T:
  # bash --version

As read is a shell builtin command there may be other commands affected.

@HerrBert - confirmed in ScPup64-20.06+2. OK in ScPup64-20.06+0 - bash 5.0.17(1).

So does FossaPup64
bash 5.0.17(1)

Thanks HerrBert.
