diffstat
显示diff命令输出信息的柱状图 ## 补充说明 **diffstat命令** 用来显示diff命令输出信息的柱状图,用以显示diff命令比较两个文件的不同统计信息。用户也可以直接使用`|`将diff命令所输出的结果直接送给diffstat命令进行统计结果的显示。使用该命令时,若所比较的文件或者子目录不在当前目录下,则应该使用其完整路径。 ### 语法 ```shell diffstat(选项)(参数) ``` ### 选项 ```shell -n<文件名长度>:指定文件名长度,指定的长度必须大于或等于所有文件中最长的文件名; -p<文件名长度>:与-n参数相同,但此处的<文件名长度>包括了文件的路径; -w:指定要输出时栏位的宽度; -v:显示版本信息。 ``` ### 参数 文件:指定保存有diff命令的输出信息文件。 ### 实例 将目录"test1"和"test2"下的同名文件"testf.txt"使用diff命令进行比较。然后使用diffstat命令对结果进行统计显示,输入如下命令: ```shell diff test1 test2 | diffstat #进行比较结果的统计显示 ``` 注意:使用这条命令可以非常方便地实现统计显示的功能。 对于查看文件中的内容,用户可以通过cat命令进行查看即可,具体操作如下: ```shell cat test1/testf.txt #查看test1/testf的内容 abc def ghi jkl mno pqr stu vws cat test2/testf.txt #查看test2/testf的内容 abc def ghi jkl mno ``` 从上面的文件内容显示,可以看到两个文件内容的差别。现在来运行刚才的命令,对文件比较的结果进行统计显示,结果如下: ```shell testfile | 2 +- #统计信息输出显示 1 file changed, 1 insertion(+), 1 deletion(-) ```
