How do I redirect command output to a file?
I have a command that I run in a folder that outputs MD5 hashes and filenames on the terminal:
hashsum
Calculate md5sum of a CD/DVD
I have an ISO file, which I burned to a CD. Now how can I check if the CD is correctly created? I would like a command that calculate the hash sum that I can use to check with the hash sum I calculate on the ISO file. Ideally the command should:
How to find the hashing algorithm used to hash passwords?
I have the working password and can see the hash (/etc/passwd). How do I find the hashing algorithm used to hash the password, without manually trying different algorithms until I find a match?
generate consistent machine unique ID
Can we generate a unique id for each PC, something like uuuidgen, but it will never change unless there are hardware changes? I was thinking about merging CPUID and MACADDR and hash them to generate a consistent ID, but I have no idea how to parse them using bash script, what I know is how can I get CPUID from
Tar produces different files each time
I often have large directories that I want to transfer to a local computer from a server. Instead of using recursive scp or rsync on the directory itself, I’ll often tar and gzip it first and then transfer it.
wpa_supplicant store password as hash (WPA-EAP with phase2=”auth=PAP”)
Is there a way to store my password in /etc/wpa_supplicant/wpa_supplicant.conf as some hash instead of plaintext?
Simultaneously calculate multiple digests (md5, sha256)?
Under the assumption that disk I/O and free RAM is a bottleneck (while CPU time is not the limitation), does a tool exist that can calculate multiple message digests at once?
Find a file when you know its checksum?
I have the md5sum of a file and I don’t know where it is on my system. Is there any easy option of find to identify a file based on its md5? Or do I need to develop a small script ?
