The man page for history says that using a negative number as the first parameter on the command line (e.g. -1000) will print the most recent (1000 in this example) lines. This isn't working with my version of bash.
Bash keeps it's history in the clear, so you should be able to run this command:
Hope this helps a bit.
EDIT:After some playing history 10000 printed my complete history (which is less than 10000 lines).

Reason: Additional info.
Does anyone know of a way to mimic the up arrow/down arrow type bash behavior within a shell script?
Say I have a scripted menu, and would like to be able to up arrow to bring up the last X number of lines of user input?
Thanks to anybody with a suggestion. :) (0 Replies)

Hi all guys,
how you can read in thread title, I'm deploying a bash script in which I have to export some variables inside it.
But (I think you know) the export command works only inside the script and so, on exit command, the variables aren't set like I set inside the script.
Consequently in... (8 Replies)

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
