This script columnates the input file, so that columns line up like in the GNU column(1) command. Its output is like that of column -t. First, awk reads the whole file, keeps track of the maximum width of each field, and saves all the lines/records. At the END, the lines are printed in columnated format. If your terminal is not too narrow, you'll get a handsome display of the file.
For an example of the output, you can try columnate -F : /etc/passwd.
{ line[NR] = $0 # saves the line for (f=1; f<=NF; f++) { len = length($f) if (len>max[f]) max[f] = len # an array of maximum field widths } } END { for(nr=1; nr<=NR; nr++) { nf = split(line[nr], fields) for (f=1; f<nf; f++) printf "%-*s", max[f]+2, fields[f] print fields[f] # the last field need not be padded } }
