intro to UNIX - making a sort-of recycle bin (for fun)
Hello, I'm only taking Intro to UNIX in school right now, so please bear with me. My problem is with a sort-of recycle-bin rig I've created for fun. I'm using Ubuntu 9.04, I am the admin. (only user, actually) of this computer. I'm using this script in ~/.bashrc
side note: I would think that checking if a directory (line 5) has contents is unnecessary, except when I just had rm -r ~/purge/* written, I'd getrm: cannot remove `/home/jzacsh/purge/*': No such file or directoryBUT only when the purge directory was empty.
Here is the output I'm seeing on login: bottom line, questions:
what am i doing wrong to get the "no such file or directory" error, in line 3 just above? (am I using variables incorrectly?)
is -ne operator only for mathematic comparisons - line 4 of error? if so, what should I use?
hello everybody,
I am trying to find the path of the Recycle Bin. I know that it's a temporary storage place, but it should have a path that we can refer to.
I want to know it because I sometimes use cygwin to work on Windows, and when you delete something with it, it's gone. I just checked... (4 Replies)
Hello,

My part is stuck... (2 Replies)

Hi,
Humorous UNIX Commands shows a fun way of using echo and dc to sort of obfuscate a string.

Hi.
I'm started to use minix 3.2.1 recently and I'm trying to create a recycle bin for it. I'm kinda struggling on how to do it. I searched internet and I found scripts created for it but I actually didn't learn how to create scripts in college and I'm not sure if I understand them. I just wanted... (1 Reply)
Hi.
I've created scripts for a recycle bin that can list, restore and empty it. I only have the problem of deleting two files with the same name. When I do it one file overwrite the other. What could I do to resolve it? The only thing I can think is asking the user to rename file before moving to... (2 Replies)

sh
sh(1) General Commands Manual sh(1)NAME
sh - Shell, the standard command language interpreter
DESCRIPTION
[Tru64 UNIX] Tru64 UNIX provides two command interpreters with the name sh. The XCU5.0 and POSIX.2 compliant command interpreter sh is
available in the file /usr/bin/posix/sh and is described in the sh(1p) reference page. The Bourne shell, historically known as sh, is
available in the file /usr/bin/sh and is described in the sh(1b) reference page.
[Tru64 UNIX] Your initial, or login, shell is determined by your entry in the file /etc/passwd. This file can be changed only by your sys-
tem administrator. You must use whatever procedures are in place at your location to have this entry changed.
[Tru64 UNIX] If available on your system, you may use the passwd -s or the chsh commands to change your login shell.
Note
This option is not available if your site manages passwords through the Network Information Service (NIS) facility. Check with your system
administrator.
[Tru64 UNIX] Subsequent shells spawned from the initial shell depend on the value in the environment variable BIN_SH. If this variable is
set to xpg4, the POSIX shell is started. If this variable is set to svr4, an SVR4 compliant version of the shell is started. If this vari-
able is unset, the Bourne shell is started. If this variable is set to any other value, an error is reported and the results are unpre-
dictable. See the EXAMPLES section for information on setting this variable.
NOTES
[Tru64 UNIX] With Tru64 UNIX Version 4.0 the Korn shell, /usr/bin/ksh is the same as the POSIX shell /usr/bin/posix/sh.
RESTRICTIONS
[Tru64 UNIX] The file /etc/shells must include entries for both the POSIX shell /usr/bin/posix/sh and the Bourne shell, /usr/bin/sh. If
this file is incorrect, see your system administrator.
EXAMPLES
Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the POSIX/ XCU5.0compliant shell, enter: BIN_SH=xpg4 export
BIN_SH Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the SVR4 compliant shell, enter: BIN_SH=svr4 export BIN_SH
Using the Bourne, Korn, or POSIX shell, to unset the variable BIN_SH, enter: unset BIN_SH Using the C/ shell, to set the variable BIN_SH to
use the POSIX/XCU5.0 compliant shell, enter: setenv BIN_SH xpg4 Using the C/ shell, to set the variable BIN_SH to use the SVR4 compliant
shell, enter: setenv BIN_SH svr4 Using the C/ shell, to unset the variable BIN_SH, enter: unsetenv BIN_SH
