for i in `ls`; doThis is a bad habit you want to get out of. If your filenames contain whitespace the script won't work. Here, this will work fine:for i in *; doMy improved for loop variable might contain whitespace, so I need to quote them "$i" Next, it's better to use $(command) rather than `command` The $(...) form can be nested. It doesn't matter here, but it's often useful. Then we have your substitutions. That's a very nice use of the shell, but "tr" is perfect:... | tr ': ' '-_'That's quote, colon, space, quote, space, quote, dash, underscore, quote "tr" replaces all colons with dashes and then all spaces with underscores. That saves a lot of typing. My final worry is that my camera can take several pictures in one second. If you have multiple pictures taken in the same second, the last one will overwrite the others. My tidied command looks like this:for i in *; do date=$(identify -format %[exif:DateTime] "$i" | tr ': ' '-_'); mv $i ${date}__$i; done
