1.批量建立文件

touch tmp_{1..10}.txt

注意大括号内是两个点，不是三个点！

结果：一次性建立如下共10个文件 tmp_1.txt tmp_5.txt tmp_9.txt

2.查找当前目录下包含某一字符的文件

find ./ -name "*_*"

结果： 所有带_的文件就显示了 /ucsc_cds ./tmp_9.txt ./tmp_3.txt ./ucsc_cds.gz ./tmp_2.txt ./tmp_1.txt ./tmp_6.txt ./tmp_8.txt ./tmp_{1-10}.txt ./tmp_4.txt ./tmp_7.txt

3.文件批量改名

find ./ -name "*_*" |while read id; do echo ${id/_/-/}; done

执行结果： ./tmp-/{1…10}.txt ./tmp-/10.txt ./tmp-/5.txt ./ucsc-/cds ./tmp-/9.txt ./tmp-/3.txt ./ucsc-/cds.gz ./tmp-/2.txt ./tmp-/1.txt ./tmp-/6.txt ./tmp-/8.txt ./tmp-/{1-10}.txt ./tmp-/4.txt ./tmp-/7.txt ./.git/COMMIT-/EDITMSG ./.git/FETCH-/HEAD

do mv 可以替代 do echo
