History 1 Aliases

By noticing the particular order number of the command in the history buffer, that command can be re-executed by typing:

!number

where number is the ordered number of that command in history buffer. The alternative way is the use of the beginning of the command. If the history buffer contained:

965 cd temp

966 mkdir mepis

967 man ftp

968 top

969 ls /var

970 cd temp

971 ls

972 cd newdir

Entering the command:

!mkd

Would cause the previous mkdir command to re-executed. By entering ! and a part of a command the shell will look back into the history buffer and will re-execute the first command that it finds that matches the part of a command that was entered.
