It's going to be quoting.

Here's a readable way to do this which largely avoids the
quoting problem:

TD=`mktemp -d`
pushd $TD
_FL1="file1_ps_-aux.txt"; sudo ps -aux > "${_FL1}"
_FL2="file2_dmesg.txt"; sudo dmesg > "${_FL2}"
_FL3="file3_printenv.txt"; sudo printenv > "${_FL3}"
kate *.txt
popd
rm $TD/*
rmdir $TD
