Getting a random file
Hello, I am very new to shell scripting. This problem seems quite easy so it should be quite easy (I hope ^^)
I want to get a random file from a directory. this file will be in one subdirectory, and it will contain spaces.
code I have got so far:
N=find ./*/*.jpg | wc -l
((N=RANDOM%N))
That gives me a number. Now I want to select the Nth file in this file list generated by find ./*/*.jpg
I wanted to use echo ./*/*.jpg except that gave me spaces as a delimiter, which is kind of stupid ^^, since file names contain spaces
