bash - 如何将包含至少一个匹配短语的所有行移动到文件末尾？

Question

如何将文件中包含至少一个匹配短语的所有行移动到文件末尾？例如，文件：

Do you like to read books?
Yes, do you like to watch movies?
No, but the fish does.

如果搜索短语是“book”和“movie”，那么上面的前两行将移动到文件的末尾，例如：

No, but the fish does.
Do you like to read books?
Yes, do you like to watch movies?

Answer 1

这是一种快速而肮脏的方法：

(grep -v -e movie -e book file; grep -e movie -e book file) >newfile

Answer 2

这是你要找的吗？

grep "match1|match2" input.txt > tmp1
grep -v "match1|match2" input.txt > tmp2
cat tmp2 tmp1 > output.txt
rm tmp1 tmp2

或者，正如凯文所指出的，不使用临时文件：

cat <(grep "match1|match2" input.txt) <(grep -v "match1|match2" input.txt) > output.txt

Answer 3

这是完整 bash 的另一种方式：

#!/bin/bash -
declare -a HEAD
declare -a BOTTOM

while read -r line
do
        case "$line" in
                *book*|*movie*)
                        BOTTOM[${#BOTTOM[*]}]="${line}";
                        ;;
                *)
                        HEAD[${#HEAD[*]}]="${line}";
                ;;
        esac    # --- end of case ---
done < "$1"

for i in "${HEAD[@]}" "${BOTTOM[@]}"; do echo $i; done
