Iterate over a list of files with spaces

Question

I want to iterate over a list of files. This list is the result of a find command, so I came up with:

getlist() {
  for f in $(find . -iname \"f         


        

Answer 1

I really like for loops and array iteration, so I figure I will add this answer to the mix...

I also liked marchelbling's stupid file example. :)

$ mkdir test
$ cd test
$ touch "stupid file1"
$ touch "stupid file2"
$ touch "stupid   file 3"

Inside the test directory:

readarray -t arr <<< "`ls -A1`"

This adds each file listing line into a bash array named arr with any trailing newline removed.

Let's say we want to give these files better names...

for i in ${!arr[@]}
do 
    newname=`echo "${arr[$i]}" | sed 's/stupid/smarter/; s/  */_/g'`; 
    mv "${arr[$i]}" "$newname"
done

${!arr[@]} expands to 0 1 2 so "${arr[$i]}" is the ith element of the array. The quotes around the variables are important to preserve the spaces.

The result is three renamed files:

$ ls -1
smarter_file1
smarter_file2
smarter_file_3
