I have a problem using bash. Simply, I cannot find the right command (if there's one!) to enter in the "- Arch_02 -" directory. As you can see, the name begins with a hyphen and this is causing some trouble:
If I use csh instead, I can regularly access the directory by issuing the command:
With bash completion, if I press tab while typing directory's name, I can also see the subdirectories under "- Arch_02 -", but cannot access them with cd!
I've got 100 directories that each have 2 directories with in them.
Structered like this:
/home/domains/domain1/
through to
/home/domains/domain100/
and those 2 directories mentioned above are here:
/home/domains/domain1/directory1/
/home/domains/domain1/directory2/

chroot
chroot(8) System Manager's Manual chroot(8)NAME
chroot - Changes the root directory of a command
SYNOPSIS
/usr/sbin/chroot directory command
DESCRIPTION
Only root can use the chroot command. The chroot command changes the root directory from / to the specified directory when the command
executes. (The command specified includes both the command name as well as any arguments.) Consequently, the root of any path (as indicated
by the first / (slash) in the pathname) changes to directory and is always relative to the current root. Even if the chroot command is in
effect, directory is relative to the current root of the running process.
Several programs may not operate properly after chroot executes. You must ensure that all vital files are present in the new root file
system and the relevant pathnames for the files map correctly in the new root file system.
For example, the ls -l command fails to give user and group names if the new root file system does not have a copy of the /etc/passwd and
/etc/group files. If the /etc/passwd and /etc/group files in the new root file system represent different user and group names, then the
output from the ls -l command will be based on those names, not the ones for the system's own name database. Utilities that depend on
description files produced by the ctab command may also fail if the required description files are not present in the new root file system.
The chroot program uses the execv() function to invoke the specified command. As a consequence, the command specified must be an exe-
cutable binary, not a shell script. Further, if the program requires indirect loading (for example, due to unresolved symbols requiring
use of a shared library), then /sbin/loader as well as any files it requires (for example, shared libraries) must be present in the new
root file system in the appropriate locations.
EXAMPLES
To run a subshell with another file system as the root, enter a command similar to the following. Note in this example, the file system is
on the /dev/disk/dsk13a device and is mounted to /mnt/dsk13a: chroot /mnt/dsk13a /sbin/sh The command shown in the previous example spec-
ifies a change from the current root file system to the one mounted on /mnt/dsk13a while /sbin/sh (which itself is relative to the new root
file system) executes. When /bin/sh executes, the original root file system is inaccessible. The file system mounted on /mnt/dsk13a must
contain the standard directories of a root file system. In particular, the shell looks for commands in /sbin, /bin, and /usr/bin (among
others) on the new root file system.
Running the /sbin/sh command creates a subshell that runs as a separate process from the original shell. Press to exit the subshell and
return to the original shell. This restores the environment of the original shell, including the meanings of the current directory (.) and
the root directory (/). To run a command in another root file system and save the output on the initial root file system, enter a command
similar to the following. Note in this example, the file system is on the /dev/disk/dsk13a device and is mounted to /mnt/dsk13a:
chroot /mnt/dsk13a /bin/cc -E /u/bob/prog.c > prep.out
The previous command runs the /bin/cc command with /mnt/dsk13a as the specified root file system. It compiles the /mnt/dsk13a/u/bob/prog.c
file, reads the #include files from the /mnt/dsk13a/usr/include directory, and puts the compiled text in the prep.out file on the initial
root file system. To create a file relative to the original root rather than the new one, use this syntax and enter:
chroot directory command > file
CAUTIONS
If special files in the new root have different major and minor device numbers than the initial root directory, it is possible to overwrite
the file system.
FILES
Specifies the command path.
