Pitfalls

Using Linux daily can provide some pitfalls. This chapter is here to make you aware.

= Searching file content = If you want to search a folder for files containing a given string, you cannot use grep -ir "whatever" * Because this will not include hidden files. Make use of the find command to build a accurate list of all files: find ./ -type f -exec grep -iH "whatever" {} \; However, for simple tasks, you can take advantage of the fact that 'hidden files' are only a naming convention, and tell grep to read all files in a directory itself: grep -ir "whatever".

= Tab completion = For tab completion problems, see tab Completion.
