The tabs program clears and sets tab-stops on the termi- nal. This uses the terminfo clear_all_tabs and set_tab capabilities. If either is absent, tabs is unable to clear/set tab-stops. The terminal should be configured to use hard tabs, e.g., - stty tab0 + stty tab0 + Like clear(1), tabs writes to the standard output. You + can redirect the standard output to a file (which prevents + tabs from actually changing the tabstops), and later cat + the file to the screen, setting tabstops at that point. --
