The variable/parameter expansion for your case in bash doesn't have that issue, so either of these work: variable=$ (ps -ef | awk '/port 10 \-/ {print $12}') variable=`ps -ef | awk '/port 10 \-/ {print $12}'` The '-' int the awk record matching pattern removes the need to remove awk itself from the search results.

first= ($ (awk (File [int (rand ()*records_count)]) )) looks like a line from shell script, not an awk script. Lose the ($ (awk ( and the ) )), then it looks like awk. Fourth: there is an awk exit command, but it is not needed in this instance. Applying all that gives:

When operating in the linux terminal I can enter the following: command ''' awk 'FNR==1 {print$5}' SNextractedstats.txt ''' To display the value in the first row and fifth column of a text file. I would like to be able to save this value as a variable in a bash script to be able to do sums and call using Echo, how would I go about doing this?

function get_row { awk -v val=$1 'NR==val {print ; exit}' list.txt } Or let shell evaluated and set the val value and print that within awk as following: function get_column { awk ' {print $val}' val=$1 list.txt } function get_row { awk 'NR==val {print ; exit}' val=$1 list.txt }

assign awk output to bash variable greetings all, I am have a heck of a time trying to accomplish a very simple thing. I have an array of "shortname<spaces>id" created from a dscl output. I want to assign shortname=word1 and id=word2. I have tried

The awk command performs the pattern/action statements once for each record in a file. For example: awk ' {print NR,$0}' employees.txt. The command displays the line number in the output. NF. Counts the number of fields in the current input record and displays the last field of the file.
