Comment on BASH: Split a string without ‘cut’ or ‘awk’ by Anton

cut works if you can manage to escape all the quotes, double and single. The built in string methods work regardless of quoting.

I'm not sure if I understand the problem, however this will split the lines regardless of how many items: 'echo $line | cut -d';' -f1- --output-delimiter=$'n'' '-f1-' will print all items starting with the first one. Notice the dash after f1. ### Output ### this “is” a command this “is” a pattern

Tim, I looked over your robot and would really like to build one. I know this post is old, but do you by any chance have the schematic to the 10kHz generator? Thanks, Lance

Comment on QNAP Technical Support, or Lack Thereof by Ed

Still a few months later, this type of crappy support still goes on. I bought my unit a year ago and the same issue happened. One ethernet port is dead. i asked for an advance replacement; willing to put a CC to insure the return. Was told I could not do that. I was forced to buy another unit, but this time it was not QNAP. I sent the other back and asked that they use my shipping account to return it to me overnight. Still, unwilling to do even that. Product is good, the support SUCKS!

Comment on read a file with bash by Anton

First off, I wrote this about 8 years ago, so a lot has changed since then including my level of knowledge. Second, lay off the useless use of cat complaints. It's simply a method of getting data for an example. In reality I would have used something like find, or recursive grep to get the data I needed to act upon. Third, this is just an example of how to loop through a file or pipe. It isn't a definitive list of things you can do inside that loop. I chose echo for simplicity, but in practice it would be whatever command you wished to perform. As for the example: find /tmp -name '*.txt' | while read line; do echo "${line}"; done That's a simple way to ensure that your loop is correct before replacing the echo with some useful command and potentially destroying data.

And as for the trying to correct the example from David. Change the two less than signs to one less than sign and then it should work. (well okay and you'll need a semi-colon before done - accidentally did not type it).
