How to loop through file names returned by find?

Question

x=$(find . -name \"*.txt\")
echo $x

if I run the above piece of code in Bash shell, what I get is a string containing several file names separated

Answer 1

If you can assume the file names don't contain newlines, you can read the output of find into a Bash array using the following command:

readarray -t x < <(find . -name '*.txt')

Note:

• -t causes readarray to strip newlines.
• It won't work if readarray is in a pipe, hence the process substitution.
• readarray is available since Bash 4.

Bash 4.4 and up also supports the -d parameter for specifying the delimiter. Using the null character, instead of newline, to delimit the file names works also in the rare case that the file names contain newlines:

readarray -d '' x < <(find . -name '*.txt' -print0)

readarray can also be invoked as mapfile with the same options.
