这篇文章给大家分享的是有关linux系统中如何使用touch命令的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

linux的touch命令不常用，一般在使用make的时候可能会用到，用来修改文件时间戳，或者新建一个不存在的文件。

适用场景:

如果创建一个新文件有很多种方法，比如:

vi filecat > fileecho "hello,world" > filetouch  filetouch命令不仅可以创建新文件，而且可以修改文件的时间属性;

格式: touch [option] [file]

备注:

\1) -t选项的时间格式[[CC]YY]MMDDhhmm[.ss]说明:\2) touch命令的几点说明:

１，同时创建一个或者多个空文件

linuxidc@linuxidc:~/linux/mkdir$ lslinuxidc@linuxidc:~/linux/mkdir$ touch a.txtlinuxidc@linuxidc:~/linux/mkdir$ lsa.txtlinuxidc@linuxidc:~/linux/mkdir$ touch b.txt c.txtlinuxidc@linuxidc:~/linux/mkdir$ lsa.txt  b.txt  c.txtlinuxidc@linuxidc:~/linux/mkdir$ touch {1..5}.txtlinuxidc@linuxidc:~/linux/mkdir$ ls1.txt  2.txt  3.txt  4.txt  5.txt  a.txt  b.txt  c.txt

2，创建文件，并用stat查看文件的属性状态信息

linuxidc@linuxidc:~/linux/mkdir$ touch linuxidc.txtlinuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 0            Blocks: 0          IO Block: 4096  regular empty filelinuxidcice: 807h/2055d    Inode: 9569451    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:25:16.439856937 +0800Modify: 2018-05-01 17:25:16.439856937 +0800Change: 2018-05-01 17:25:16.439856937 +0800Birth: -最后有３个时间Access time: 最后访问时间，查看文件的内容时，这个时间会改变，使用cat命令查看文件时，可以看出Access time已经变了linuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 0            Blocks: 0          IO Block: 4096  regular empty filelinuxidcice: 807h/2055d    Inode: 9569451    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:25:16.439856937 +0800Modify: 2018-05-01 17:25:16.439856937 +0800Change: 2018-05-01 17:25:16.439856937 +0800Birth: -linuxidc@linuxidc:~/linux/mkdir$ cat linuxidc.txtlinuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 0            Blocks: 0          IO Block: 4096  regular empty filelinuxidcice: 807h/2055d    Inode: 9569451    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:27:51.887215139 +0800Modify: 2018-05-01 17:25:16.439856937 +0800Change: 2018-05-01 17:25:16.439856937 +0800Birth: -Modify time:最后修改时间，修改文件内容，文件的修改时间会改变。访问时间和状态改变时间 也发生变化linuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 0            Blocks: 0          IO Block: 4096  regular empty filelinuxidcice: 807h/2055d    Inode: 9569451    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:27:51.887215139 +0800Modify: 2018-05-01 17:25:16.439856937 +0800Change: 2018-05-01 17:25:16.439856937 +0800Birth: -linuxidc@linuxidc:~/linux/mkdir$ vim linuxidc.txtlinuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 5            Blocks: 8          IO Block: 4096  regular filelinuxidcice: 807h/2055d    Inode: 9569550    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:29:34.982228802 +0800Modify: 2018-05-01 17:29:34.982228802 +0800Change: 2018-05-01 17:29:35.018231392 +0800Birth: -Change time:状态改变时间,修改文件内容，移动文件，或者改变文件属性等，文件的change time会发生改变.１，移动文件( 重命名 ), change time 发生改变:linuxidc@linuxidc:~/linux/mkdir$ stat linuxidc.txt File: 'linuxidc.txt' Size: 5            Blocks: 8          IO Block: 4096  regular filelinuxidcice: 807h/2055d    Inode: 9569550    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:29:34.982228802 +0800Modify: 2018-05-01 17:29:34.982228802 +0800Change: 2018-05-01 17:29:35.018231392 +0800Birth: -linuxidc@linuxidc:~/linux/mkdir$ mv linuxidc.txt linuxidc2.txtlinuxidc@linuxidc:~/linux/mkdir$ stat linuxidc2.txt File: 'linuxidc2.txt' Size: 5            Blocks: 8          IO Block: 4096  regular filelinuxidcice: 807h/2055d    Inode: 9569550    Links: 1Access: (0664/-rw-rw-r--)  Uid: ( 1000/ linuxidc)  Gid: ( 1000/ linuxidc)Access: 2018-05-01 17:29:34.982228802 +0800Modify: 2018-05-01 17:29:34.982228802 +0800Change: 2018-05-01 17:32:25.392863791 +0800

3，修改文件的权限，change time发生了改变
