這篇文章給大家分享的是有關linux系統中如何使用touch命令的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。
linux的touch命令不常用，一般在使用make的時候可能會用到，用來修改文件時間戳，或者新建一個不存在的文件。
如果創建一個新文件有很多種方法，比如:
vi file cat > fileecho "hello,world" > file touch file touch命令不僅可以創建新文件，而且可以修改文件的時間屬性;
格式: touch [option] [file]
備注:
\1) -t選項的時間格式[[CC]YY]MMDDhhmm[.ss]說明:\2) touch命令的幾點說明:

linuxidc@linuxidc:~/linux/mkdir$ touch b.txt c.txt
linuxidc@linuxidc:~/linux/mkdir$ ls
a.txt b.txt c.txt
linuxidc@linuxidc:~/linux/mkdir$ touch {1..5}.txt
