For example, to extract characters 1 through 11 and the 56th character onward from a detailed directory listing, use the following command:ls -l | cut -b 1-11,56- | more total 2056 -rw-r—r— a2ps.cfg -rw-r—r— a2ps-site.cfg -rw-r—r— adjtime drwxr-xr-x aep -rw-r—r— aep.conf -rw-r—r— aeplog.conf drwxr-xr-x alchemist -rw-r—r— aliases -rw-r——- aliases.db (... lines deleted)
