bash dir string construction from command in one line

dir=$(pwd; echo '/hi/'; date "+%Y_%m_%d-%H_%M_%S")

echo $dir

gives 

/some/path/hear /hi/ 2014_11_30-12_40_17

Why are there spaces ? how to make this path in one line with out spaces ?

Thanks

This still works as well:

$ dir=`pwd`/hi/$(date '+%Y_%m_%d-%H_%M_%S')
$ echo $dir
/home/oracle/hi/2014_11_30-14_18_30
$

Funny there are so many ways of doing this

Use printf.

$ printf '%s/hi/%s\n' "$(pwd)" "$(date "+%Y_%m_%d-%H_%M_%S")"
/home/path/hi/2014_11_30-07_53_05

Easiest way, I think:

dir="$(pwd)/hi/$(date '+%Y_%m_%d-%H_%M_%S')"

the $() expressions work just like normal variables in this context.

You could use sed.

$ dir=$(pwd; echo '/hi/'; date "+%Y_%m_%d-%H_%M_%S")
$ dir=$(sed 's/ //g' <<< $dir)
$ echo $dir
/home/path/hi/2014_11_30-18_21_09
