Hey Chris,

It looks like just a simple typo in Aia's reply. Just change $8.2f to %8.2f and you should get "1.20"

Hey Richard,

For both of those, you can capture the output of your test commands using backticks (will work in any shell) or the $() test in bash

For instance, you could take your statement:
...

Hey,

Glad I could help. In the process, you taught me a cool trick. I never knew you could do that... all those years.... exiting over and over again just to get out of a terminal session. It...

Hey there,

Sometimes it will work if you just replace your exec call with a simple direct call, so instead of:



just do

<-- Since you're not exec'ing (i.e. replacing the current process...

Hey there,

This should work:



Best wishes,

Mike

Hey There,

You're probably running into an issue with -p if you're just using a plaintext password. It expects the password to be encrypted using the crypt program (apologies if my assumption is...

Hey there,

That can be done. Try this first though, since I find that "human readable" output is usually off. I would grab the information in kb and convert that to Mb. It will probably be more...

Hey There,

You coud use the output of format, although if you wanted to automate, you'd have to pipe the right commands to it and then do some processing on the other end, eg, for disk 0:


...

Hey There,

Two things, I think:

1. You're not stripping the literal dollar sign from the figures you're trying to add

2. Since you're invoking awk twice, you need to include your BEGIN...

Also, as Salem pointed out, don't forget to use the preceding $ character when you're extracting values from your variables.

Best wishes,

Mike

Aia is correct about crontab -e. It does do checking, which is why I put that at the other end of the pipe :)

Basically the reason your script failed is that you need to actually put the control...

Hey, Great - I hope it works out :)

Just to answer your questions:

mgolvach@tlaum-pc1 ~ is just my command prompt from my x86 linux box

The DO NOT COPY header is put in there by crontab. ...

Hey There,

You should be able to do this with vi (assumming your EDITOR environment variable is set to vi).

First, check out this article on how to "really" insert control characters into your...

Hey There,

I think your problem has to do with the "echo" that you're using (shell built-in vs. the binary). I'd guess that on this line, the echo doesn't accept the -e and -n arguments and is...

Hey There,

Just a suggestion. If you're using Gnu Sed, you can use the -i option and it will do the changes inline (basically taking care of writing to a tmp file and then copying back, which Aia...

Hey There,

Forgetting about what the "ls" variable evaluates as, it's a pretty simple expression that just looks confusing. It's using expr's ":" string comparison operator.

on the left side...

Glad to hear it :)

Best wishes to you,

Mike

Hey There,

Unless it's a permissions issue (where you can't delete the folders as the user that runs the batch file) is it possible that you're trying this at the command line as proof-of-concept...

Hey There,

You can catch tabs with sed using escape characters. So far tabs, you could match it with:



Hope that helps and best wishes,

Mike

Hey there,

One way to pass variables to awk (so you don't have to use double quotes) is with the -v flag, like



and then you could use the variable rBytes1 in your script just like any other...

Hey there,

Some excellent suggestions from Fest3er, as well :)

For your version, you may need to include a space. My (non-Gnu) version likes me not to include a space, but I've used Gnu xargs...

Hey there,

You could also just slap it all together on one line and forget about the output file. Try this and let me know if I fat-fingered any of it - this should all be one line if it gets...

Actually, either way it's just a normal process. I guess the distinction to be made is that "job control" manages processes and refers to them as jobs. Every job is a process (possibly more than...

Hey there,

process/job - terms are sometimes misused or mixed up in regular reference to them, in everything from regular conversation to official text books.

For awk, who, etc, you can run any...

Hey again,

In that case it might just be simpler to do:

sed -e 1,2d -e 6d FILENAME

The reason the command above removes any line starting with a pound is that I write answers in too many...

Hey There,

If you just want to delete files that (I'm assuming) begin with a pound character and start with ifndef,define or endif, you could do it (not very generically in this example) by using...

Hey There,

Your pretty much good, but I just use octals:

so generic file =
644
110 100 100

umask
123

Hey there,

To run them in the foreground, as Salem suggested, just remove the trailing ampersand on all your mdadm commands, so:

mdadm --manage /dev/md0 --add /dev/sdb1 &

becomes

mdadm...

I'm in agreement with Salem, run that file through a quick awk statement to parse it into field based on the tabs and see what you get. It might be the answer you're looking for.

If you have...

Hey There,

If there's any sort of delimiter at all between the fields (for instance, a colon), you can use awk's -F option, like:



and so forth,

Best wishes,

Nice creative fix. Good show!

Hey There,

Inside the double quotes, in your test statement, the single quotes are being treated as literal characters in the value of the filename variable:

If you just change



to

Hey There,

You should be good to go with just a little change-up:



Hope that helps you out :)

Hey There,

I'm using FreeBSD 4.1 right now and got it to work by just wrapping the regular expression in quotes. It may be that your shell is interpreting the * character before it passes it to...

Hey there,

It may just be an issue with calling the variables.

If you change



to

Hey there,

You just need to change the



to

Hey THere,

Your initial shot was pretty close. Just change:



to

Hey There,

You can use expr's colon (:) notation for string comparison, but it might be easier to read and write to do something with grep, like:

echo $1|grep "/" >/dev/null 2>&1

(use -q for...

Hey again,

To my knowledge there's no currency routine or built-in in the bash shell, but you could write a function to take care of it.

Also, if this helps, check out this manpage for "units"...

No problem,

And thanks for overlooking the fact that I spelled event "even" ;)

I've gotta cut back on the speed-typing ;)
