I need to download multiple files from an FTP server but occasionally they arrive in error so I need to perform an integrity check. I've been attempting to write a bash script that does the following:
Downloads all files including those in sub directories
Perform md5sum using stored hash values
Download any files that fail the integrity check again
Repeat steps 2-3 until all files have passed the integrity check
I'm stuck on step 3. I don't know how to download the individual file so that it goes into its relevant sub-directory by itself. The relevant parts of my files and script are as follow:
This ofcourse stores the file in the working directory. For instance, I'd like two.txt to save to /working directory/a/b/. Any ideas? Additionally, is there a better way of doing this?
Hi all,
I am kinda puzzled. When and Why do we use md5sum? I've read man pages for mp5sum, but didn't get anything out of it. Please, can someone explain this to me in couple of words.
Thank you all. (1 Reply)

Ok, I run a small script, that restarts a perl script when it fails (it's a very unreliable perl script, but I can't change it, it's crucial, and I don't know perl)
It outputs data into a logfile. Unfortunately, it also regularly hangs. This is a major problem because if it hangs, no data is... (6 Replies)

So basically, I'd start with a:

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.
