I know "awk -F:" will separate out the column by ":" , now if I what to separate out the column by space also , what can I do ?
for example :
#ps -ef |grep telnet
how to separate out the column so that the column as below,
column 1 --> root
|awk {print $12} then output the result is 192.168.0.1 , in short , I want to separate the column , to let the column is separate by : and space at the same time like my above example , is it possible ? thx
ps -ef |grep telnet | tr ":" " " | awk ' { for ( i=1; i<=NF; i++ ) { print $i; }}'
awk 'BEGIN{FS="[ :]+"}{for(i=1;i<=NF;i++)print $i}'
Hi ...
I tried this out in one of my files having the data as below
20051202 07:02:03 07:38:23
But it still gives result as below .... it was not taking FS as either space or colon ...
$ awk 'BEGIN{FS="[ :]+"}{print $1}' filename
just change awk to nawk and it works fine....
Great .... that worked fine ... thanks a lot ....
i think nawk has the capability of taking regular expressions as field seperator which awk does not have .... am i right ?
from man nawk
FS Input field separator regular expression; a space
you are correct.
