I've had Linux when I was young, on one of our first computers and learned it pretty quickly... However, I've been working on Windows for about 7 years now and just made the switch back to Linux, Mandrake 9.1. So I have some problem with creating new user accounts. I could create one, but once I... (3 Replies)

I have a directory full of zip files.
How would I write a bash script to enumerate all the zip files, remove the ".zip" from the file name, create a directory by that name and unzip each zip file into its corresponding directory?
Thanks!

I have a script on about 15 hosts that I need to run for each host whenever I want (not crontab). Problem is, this script takes 5-10 mins to run for each host. Is there a way I can run the script in parallel for all the hosts instead of 1 at a time? Also, I'm remotely running the script on the... (3 Replies)
I have a script to detect if a host is pingable or not. The problem is that I would like it to put the nonpingable hosts in one file and the pingable hosts in another. I have come up with this so far:

Hi everyone!
Some time ago, I had to check connectivity with a big list of hosts, using different formats (protocol://server:port/path/, server:port, ....).
I developed a script that checks the connectivity using different commands (ping, telnet, nc, curl).
It worked for me so I'm sharing it... (9 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 filename 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.
