Hi lfa2,
To put output in a 2nd file:
perl -lane 'print "$F[0] $F[1] $F[3] $F[2]"' infile.txt >outfile.txt
To modify the input file:
perl -i -lane 'print "$F[0] $F[1] $F[3] $F[2]"' infile.txt
To put output in a 2nd file:
perl -lane 'print "$F[0] $F[1] $F[3] $F[2]"' infile.txt >outfile.txt
To modify the input file:
perl -i -lane 'print "$F[0] $F[1] $F[3] $F[2]"' infile.txt
Or more concisely:
perl -lane 'print "@F[0,1,3,2]"' infile.txt >outfile.txt
or:
perl -i -lane 'print "@F[0,1,3,2]"' infile.txt
perl -lane 'print "@F[0,1,3,2]"' infile.txt >outfile.txt
or:
perl -i -lane 'print "@F[0,1,3,2]"' infile.txt
