I am a newbie in Unix. I have a requirement in which I have to put the output of find statement in array because later in the script I have to use the output lines one by one. My find statement will retrieve me the location of directories based on the condition.

Here are the find statements:

find blah -mindepth 3 -maxdepth 3 -type d  -regex ".*/V[0-9]+/wsdls+" 
  • i got a solution for this.. array=($(find blah -mindepth 3 -maxdepth 3 -type d -regex ".*/V[0-9]+/wsdls+")) i=0 for file in "${array[@]}" do echo "${file}" let i++ done but here the strange thing is after executing this though i am able to see data properly but in every line it's saying i++ is not a valida command..and as soon as i removed the i++, then it gave me the data properly..my question is how it is happening as we are not increasing the value of i.. – Ankit Apr 20 '11 at 12:10

  • hard to give you help when we can't see the newlines in your code. Please put it in an answer. – glenn jackman Apr 20 '11 at 13:21

You can do this:

array=( $(find blah -mindepth 3 -maxdepth 3 -type d -regex ".*/V[0-9]+/wsdls+") )

# loop over it
for i in ${array[@]}
    echo $i

# or in a while loop
while [ $i -lt ${#array[@]} ]
    echo $i: ${array[$i]}

    You'll need to set IFS=$'\n' first though: in case any of the filenames have spaces, you want to keep them as a single array element. The you'll also want to use double quotes when referencing the array: for i in "${array[@]}" – glenn jackman Apr 20 '11 at 13:15

    This is quite old, but this should have been the accepted answer. It works out quite well, and the comment from @glennjackman is also quite useful. – casper Sep 7 '18 at 16:31

    A clarification to @glennjackman's answer is that the IFS=$'\n' needs to be at the start of the assignment statement, not in the find subshell; e.g. IFS=$'\n' array=(...). – devstuff Nov 13 '18 at 1:30
