如何使用相应的空格字符数替换制表符？ （在linux中）

Question

I am planning on replacing all of my tab characters in a certain file with the corresponding number of space characters in a shell. Tried using tr and sed, but none seem to work out. Any suggestions?

Answer 1

Have you tried expand ? Usage is:

$ expand  <FILE_WITH_TABS> > <FILE_WITH_NO_TABS>

You can also modify tab width using -t option. For example, to change from the default width to 2:

$ expand -t 2 <FILE_WITH_TABS> <FILE_WITH_NO_TABS>
