Search Results

Thank you, that works!
One slight problem however. When I run the code from the parent directory, and say: (edited to be more specific)


#!/bin/ksh

cd /path/
if [ ! -f file ]; then
echo...

I want to write a script to see if various files exist. What I want to do is have the script search in various directories if a file exist, and if not, then output something like "/path/file does not...

It's actually quite long, so it would not be a good idea to post all of it. The first two values are here:

0.002077
0.038983

All values are give to this precision. So clearly in this case both...

Yes, I did get it to work using awk.
As noted, if someone can tell me why Ygor's code did not work, I would like to know. Thanks for everyone's help!

Thanks, it looks like it should work, but unfortunately nawk does not work, since I get:

-bash: nawk: command not found

... so, if possible it would be great to get the code Ygor started on...

Thanks Ygor, that *almost* works!

1)What's the difference between bash and ksh and is one better than the other?

2)if [ "$(echo...

On line 29 I have:

read a b < temp_star1

I have a lot of comments before that, and a few simple shell commands that should not affect anything. I just noticed I am using

#!/bin/bash
...

I'm not sure what the above expression does, but it did work for the case when a < b, however when a > b I get:

line 29: [: : integer expression expected

Thanks for the quick reply!
Very helpful. Quick follow-up question. I don't know if this matters, but my values are not necessarily integers, and I got this warning:

line 21: [: 5.039814: integer...

Hello, I have a quick question that is not related to homework in any way shape or form (in case anyone wanted to know). My question is thus:

I have a file "temp" that has the two values say "5"...

Corona, thank you very much! That's very useful :)

Much thanks!

Hello, I have a simple(I think) question!
Although simple, I have been unable to resolve it, so I hope someone can help! OK, here it is:

1)I have an awk script that prints something, such as:...
