If user is always the first field and resources_used.walltime is always the last, then:
sed -e 's/ .* / /'will do the job.

Could you set up sudo rules to allow this. There is a NOPASSWD option you can add to them and you command would become:-sudo su - ${test_account} -c "check_accounts.sh"


Does this help?


...

The reason it does this is because it's designed to not allow exactly what you are trying to do -- because it's an extremely bad idea. It's almost impossible to keep stored plaintext passwords safe.

And what exactly do you mean by "priority order"?

I don't believe that you can do that, I've checked the man pages and haven't found anything.

I don't believe there is a way to do this with the chkconfig command, but you could try listing and sorting the contents of the /etc/rc.d/rc.*d directories to create an ordered list by priority of...

Hi hce,

To get the most popular tool, you'd have to carry out an in depth survey.

I thought you'd just want one that would do the job.

Operating system is irrelevant, memtest86 is a standalone tool. It literally needs no operating system at all(in fact, one would get in the way) -- it only requires a bootloader. It seems to come...

Hi hce,

Have used this (https://sites.google.com/site/itmyshare/system-admin-tips-and-tools/memory-test-tools-on-centos-rhel-and-other-linux) in the past, did the job for me.:)

Rename them then reboot. Be sure to have a rescue disk handy...

Try this: in modprobe.d create a new file called 8021q. In it, put the lines:
install 8021q /bin/true
install garp /bin/true


This tells the kernel to use non-standard versions of 8021q and...

Check if ssh-keygen on your system supports the -F option. It is used to find hashed hostnames in known_hosts files.

As the user that has been added to a new group issue:

$ newgrp <new_group>

Change back to your primary group
$ newgrp
Test
$ groups

Add tou your ssh:
-o ConnectTimeout=n
Where n is compute as seconds.

In addition to what Scrutinizer said, $7 in the last line of output from dd is s,; not 60.6 MB/s. And you don't need both grep and awk. Try:
dd if=/dev/zero of=/dev/null bs=1G count=1 oflag=dsync...

Try:
dd .... 2>&1 | grep ....

--edit--

$ cat <<test | grep -w 'compute'
" properties = local compute"
" properties = local bigcompute"
test

" properties = local compute"

That's UUOC, could be simply <<test grep -w

-w is an extension to POSIX grep and is not available on every platform. An alternative that should work in any POSIX grep would be:

grep -E '([^[:alnum:]_]|^)compute([^[:alnum:]_]|$)' file

Then try this:
grep -E 'properties =.*[^[:alnum:]_]compute([^[:alnum:]_]|$)' file

If it does not need to be portable, on some platforms you can also try one of the following:
grep 'properties...

Yes, command line options are for ssh, and they override ssh_config.
For changing existing options in sshd_config you can use awk
file=/etc/ssh/sshd_config
cp -p $file $file.old &&
awk '...

Here is a much more verbose awk script that I think does what you want.
#!/bin/ksh
tmp="rm_tmp1.$$" # tmp file to hold sorted ouput list of normalized

I personally would not run commands like fdisk that way, at the risk of screwing up a disk.
It is your disk, so:
in UNIX you create a script using a here document:

fdisk -u -p /dev/whatever...
