Commands, Syntax, and Examples The awk command is powerful method for processing or analyzing text files, in particular data files that are organized by lines (rows) and columns. Simple awk commands can be run from the command line. More complex tasks should be written as awk programs (so-called awk scripts) to a file. The basic format of an awk command looks like this: awk 'pattern {action}' input-file > output-file This means: take each line of the input file;
awk -F, '{ print $3 }' table1.txt > output1.txt
awk '$7=="\$7.30" { print $3 }' table1.txt
awk '/30/ { print $3 }' table1.txt
awk '{ sum=0; for (col=1; col<=NF; col++) sum += $col; print sum; }'
