正如Kevin已经在上面的答案中发布的那样，最好的解决方案是使用bash glob的for循环，但由于bash glob默认情况下不是递归的，这可以通过bash递归函数来修复:

#!/bin/bash
set -x
set -eu -o pipefail

all_files=();

function get_all_the_files()
{
    directory="$1";
    for item in "$directory"/* "$directory"/.[^.]*;
    do
        if [[ -d "$item" ]];
        then
            get_all_the_files "$item";
        else
            all_files+=("$item");
        fi;
    done;
}

get_all_the_files "/tmp";

for file_path in "${all_files[@]}"
do
    printf 'My file is "%s"\n' "$file_path";
done;

根据@phk的其他回答和评论，使用fd #3: (仍然允许在循环中使用stdin)

while IFS= read -r f <&3; do
    echo "$f"

done 3< <(find . -iname "*filename*")

查找<path> -xdev -type f -name *.txt -exec ls -l {} \;

这将列出文件并给出有关属性的详细信息。

# Doesn't handle whitespace
for x in `find . -name "*.txt" -print`; do
  process_one $x
done

or

# Handles whitespace and newlines
find . -name "*.txt" -print0 | xargs -0 -n 1 process_one

我喜欢使用find，这是第一次分配给变量和IFS切换到新行如下:

FilesFound=$(find . -name "*.txt")

IFSbkp="$IFS"
IFS=$'\n'
counter=1;
for file in $FilesFound; do
    echo "${counter}: ${file}"
    let counter++;
done
IFS="$IFSbkp"

正如@Konrad Rudolph所评论的那样，这将不适用于文件名中的“新行”。我仍然认为它很方便，因为它涵盖了需要遍历命令输出的大多数情况。

(更新到包括@Socowi的卓越速度提升)

使用任何支持它的$SHELL (dash/zsh/bash…):

find . -name "*.txt" -exec $SHELL -c '
    for i in "$@" ; do
        echo "$i"
    done
' {} +

完成了。

原来的答案(更短，但更慢):

find . -name "*.txt" -exec $SHELL -c '
    echo "$0"
' {} \;
