问题描述
我试图写一个小脚本,这将打开一个文本文件,并给我的每一行文本的MD5哈希值。比如我有一个文件:
I'm trying to write a little script which will open a text file and give me an md5 hash for each line of text. For example I have a file with:
123
213
312
我想输出是:
ba1f2511fc30423bdbb183fe33f3dd0f
6f36dfd82a1b64f668d9957ad81199ff
390d29f732f024a4ebd58645781dfa5a
我试图做这部分在bash这将读取每一行:
I'm trying to do this part in bash which will read each line:
#!/bin/bash
#read.file.line.by.line.sh
while read line
do
echo $line
done
后来我做的:
$ more 123.txt | ./read.line.by.line.sh | md5sum | cut -d ' ' -f 1
但我在这里失去了一些东西,不工作:(
but I'm missing something here, does not work :(
也许还有一个更简单的方法...
Maybe there is an easier way...
推荐答案
快到了,试试这个:
while read line; do echo -n $line|md5; done < 123.txt
除非你也想在哈希每行换行字符,你应该包括-n选项。
Unless you also want to hash the newline character in every line you should include the '-n' option.
在一个脚本:
#!/bin/bash
while read line; do echo -n $line|md5; done < $1
