I'm trying to write a little script which will open a text file and give me an md5 hash for each line of text. For example I have a file with:
123
213
312
I want output to be:
ba1f2511fc30423bdbb183fe33f3dd0f
6f36dfd82a1b64f668d9957ad81199ff
390d29f732f024a4ebd58645781dfa5a
I'm trying to do this part in bash which will read each line:
#!/bin/bash
#read.file.line.by.line.sh
while read line
do
echo $line
done
later on I do:
$ more 123.txt | ./read.line.by.line.sh | md5sum | cut -d ' ' -f 1
but I'm missing something here, does not work :(
Maybe there is an easier way...
You can just call md5sum directly in the script:
That way the script spits out directly what you want: the md5 hash of each line.
Almost there, try this:
Unless you also want to hash the newline character in every line you should use
printf
orecho -n
instead ofecho
option.In a script:
The script can be called with multiple files as parameters.
