Hi all: I'm doing an audit of some Linux machines, and have used this awk one-liner to find accounts with uid > 499: awk -F: '{if ($3 > 499) print $0}' < /etc/passwd It works great if you run it on a host directly, but if I try to ssh to a remote host and run the command it fails: mybox$ ssh servername awk -F: '{if ($3 > 499) print $0}' < /etc/passwd bash:

Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value.

Hey guys, Looking through my book and the web and I am not having any success returning data from a search. I need to have awk search for a string and print the first field which is no problem but now its returning two options as the input data has changed. The change is reliable, I only want the first field if it ends in a regex that I have, and I only want what that regex matches to be printed.

This snippet of code pulls an array of hostnames from some log files. It has to parse around 3GB of log files, so I'm keen on making it as efficient as possible. Can you think of any way to optimize this to run faster? HOSTS=() for host in $(grep -h -o "[-\.0-9a-z][-\.0-9a-z]*.com" ${TMPDIR}/* | sort | uniq); do HOSTS+=("$host") done

Trying to avoid a perl script which wouldn't be hard, but I am looking for an awk one liner that does a replacement, but only after it sees a key word on some line. Anyone know of that's easy to do? Thanks! jlc

Can anyone point me to a how to or beginners guide to setting up LDAP authentication on CentOS5 with replication?

In our environment we have many legacy application servers running apache/jserv. There is a web server front end, then a couple of load-balanced java servers on the backside. One of the problems we are faced with is hung or stuck jvms. I have looked at the java process with the ps command, and there are many times when URL(s) do not respond, yet the java looks healthy, at least from the OS

a little out of my comfort zone and have practically gotten what I want but awk seems determined to send a message via std error which is problematic and annoying. Basically trying to get a list of virtual host names from nginx config files like this: $ awk -F" " '/./ { if ( match ( "^server_name$", $2 ) ) print $1 }' /opt/nginx/sites/*.conf \ | grep -v server_name |

It might not be rare, but it's certainly less universally available than awk, which is preinstalled on pretty much every unix-like OS out there. > There are many flavours of AWK.

This replaces the build dependency on perl with one on awk which is already used in the build system and is much more ubiquitous than perl --- Makefile.in | 2 +- mkproto.awk | 39 +++++++++++++++++++++++++++++++++++++++ mkproto.pl | 48 ------------------------------------------------ 3 files changed, 40 insertions(+), 49 deletions(-) create mode 100644 mkproto.awk delete mode 100644

Hi I am sure the answer here is really easy but i am stuck! # mount | grep data | awk '{print$1,$2,$3}' gives me the info i require locally, however i need to execute this over about 1000 hosts so i run things remotely using ssh something like # MOUNTER=`ssh $i 'mount | grep data | awk '{print$1,$2,$3}''` however this fails as at the end of the line there are 2 ticks

In clinical trial data preparation and many other data situations, the statistical programmer needs to merge and re-merge multiple input files countless times. A syntax for merging files that is clear and concise is very important for the statistical programmer's productivity. Here is how Vilno does it: inlist dataset1 dataset2 dataset3 ; joinby variable1 variable2 where ( var3<=var4 ) ;

I have csvde dump from active directory I process on my postfix mta.

This is odd, and annoying. CentOS 6, current. Here's my awk script: { room = substr($0, 48, 10); arr[$2,room,$1] = $0; } END { for ( i in arr ) { for ( j in arr[i] ) { for ( k in arr[i][j] ) { print arr[i][j][k]; } } } } And when I run it, it complains awk -f awksort proplist7 awk: awksort:7: for ( j in arr[i] ) { awk: awksort:7:
