GLOBIGNORE变量的意义
关于GLOBIGNORE的意义可以通过查看bash的man手册来看到:
A colon-separated list of patterns defining the set of filenames to be ignored by pathname expansion. If a filename matched by a pathname expansion pattern also matches one of the patterns in GLOBIGNORE, it is removed from the list of matches.
它可以用来防止误删除某些文件.
比如,假设我们希望谨慎地删除那些隐藏文件,那么我们可以这样设置
GLOBIGNORE=.*
这样一来,用 rm * 就不会删除这些隐藏文件了, 你甚至不能用任何通配符的方式来删除这些隐藏文件,唯一能删除这些文件的方法只能是明确地输入完整的名字.
