As I use/try/test many shells, I'm in the habit of using POSIX commands such as 'fc -l 1' to list the complete history. If there have been more than $HISTSIZE command, the list is trimmed at the beginning without renumbering, and bash errors out: $ fc -l 1 bash-5.0: fc: history specification out of range This is different from every other shell, and also looks like it's contrary to the POSIX spec: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/fc.html#tag_20_44_05 | When a range of commands is used, it shall not be an error to specify | first or last values that are not in the history list; fc shall | substitute the value representing the oldest or newest command in the | list, as appropriate. For example, if there are only ten commands in | the history list, numbered 1 to 10: | | fc -l | fc 1 99 | | shall list and edit, respectively, all ten commands. The attached patch removes the error and limits the range to available commands as specified. - Martijn -- || modernish -- harness the shell || https://github.com/modernish/modernish || || KornShell lives! || https://github.com/ksh93/ksh
