testing - BASH test exist directory with a variable as path -

i simple test know if directory exist in bash script.
directory path in variable.
test works path of file not work variable.

 # if [ -d $test ]; echo ok; fi   # >> ### no output ###  # if [ -d ~/dir/ ]; echo ok; fi   # >> ok  # echo $test  # >> ~/dir/

i define variable mysef :

 # test="~/dir/"

i don't understand why not work variable whereas contains same path.

thanks

your test doesn't work variable because contains tilde (~).

you can use eval recommended approach use ${home} instead of ~ in variable. try:

test="${home}/dir" [[ -d $test ]] && echo ok
