There are as many ways to solve this quirky echo problem as there are pages in this book. One of my favorites is very succinct:
function echon
{
echo "$*" | awk '{ printf "%s" $0 }'
}You may prefer to avoid the overhead incurred when calling the awk command, however, and if you have a user-level command called printf you can use it instead:
echon()
{
printf "%s" "$*"
}But what if you don't have printf and you don't want to call awk? Then use the tr command:
echon()
{
echo "$*" | tr -d '\n'
}This method of simply chopping out the carriage return with tr is a simple and efficient solution that should be quite portable.
