How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

rm x*first and then simplyfor i in x*; do cat $x | tee /dev/tty; done | ed. I will probably feel most comfortable adapting Mark's answer withprintf '%s\n' "$line"instead ofecho "$line", removingIFS=as there's only one variable and changingsleep 0.5tosleep 0(noticing the many options you said I would have). I learned a lot with your feedback! Thanks!IFS=is there, even if the whole line is to be read into a single variable. Some information may be lost. Unlikely in this case, but nice to know this best practice. If I may ask, did you pick all of this up "by doing and learning", or was there a single source/book that you followed carefully and would suggest. Thanks once more! Happy 2015!split(1). Yes, I'd be inclined to delete all files beginning with x, maybe in a temporary directory. I'm pretty suresplit(1)generates file names in alphabetical order, so thatcat $x*gives you back the original file. I've used it in that basic way a few times. The UNIX founders got a lot of things right!
