Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

(1) don't run twice, or the same folder will occur in $PATH.

(2) otherwise you need to start a new terminal

CLASSPATH=.; export CLASSPATH=$CLASSPATH$(find "$PWD" -name '*.jar' -type f -printf ':%p\n' | sort -u | tr -d '\n'); echo $CLASSPATH
echo "Simplied Chinese:"; while read -r line; do echo "Traditional Chinese:"; echo $line | iconv -f utf8 -t gb2312 | iconv -f gb2312 -t big5 | iconv -f big5 -t utf8; done
sort -t"," -n -k5 file.csv # according to the 5th field NUMERICALLY!!

Pros: the format is very simple, there is no need to show every columns, and full command with args

the first column is memory consumption %

the second column is pid

the third is just the command (without full arguments, most application's arguments are too long)

You can decide which application to kill then.

pdsh -R ssh -w se00[1-5] # a list of host names

Functions: host ssh

parrallel execution of a command on remote host by ssh or rsh or ...

very useful for cluster management (software update)

killall -r 'a regular expression'

Functions: killall

This is usefull when we don't know the exact name of the process, but the application name

A limitation is that the regular expression only tries to match the last part of the full command (i.e. the bin file name itself).

But this is way shorter than the following one:

ps axww | grep SomeCommand | awk '{ print $1 }' | xargs kill
