`find / xyz / abc / music / | grep def`

If you only need the first element (or rather the line), you can use head :

 `find /xyz/abc/music/ |grep def | head -n 1`

If you need access to arbitrary elements, you can first save the array and then extract the element:

 arr=(`find /xyz/abc/music/ |grep def`) echo ${arr[n]}

but this will not cause each line of the grep output file to be split into a separate array element.

If you need whole lines instead of words, you can use head and tail for this task, for example:

 `find /xyz/abc/music/ |grep def | head -n line_number | tail -n 1`

Place a call to find in array brackets

 X=( $(find /xyz/abc/music/ | grep def) ) echo ${X[1]} echo ${X[2]} echo ${X[3]} echo ${X[4]}

Although a little late, the best solution should be the answer from Ray, but you will have to rewrite the default IFS environment variable for IFN for the new line to enter the complete lines as an array field. After filling the array, you should switch the IFS to the original value. I will reveal the Rays solution:

 # keep original IFS Setting IFS_BAK=${IFS} # note the line break between the two quotes, do not add any whitespace, # just press enter and close the quotes (escape sequence "\n" for newline won't do) IFS=" " X=( $(find /xyz/abc/music/ | grep def) ) echo ${X[1]} echo ${X[2]} echo ${X[3]} echo ${X[4]} # set IFS back to normal.. IFS=${IFS_BAK}
# keep original IFS Setting IFS_BAK=${IFS} # note the line break between the two quotes, do not add any whitespace, # just press enter and close the quotes (escape sequence "\n" for newline won't do) IFS=" " X=( $(find /xyz/abc/music/ | grep def) ) echo ${X[1]} echo ${X[2]} echo ${X[3]} echo ${X[4]} # set IFS back to normal.. IFS=${IFS_BAK}

Hope this helps
