Transpose CSV files
If you need to transpose your CSV matrix before using it (i.e., rows->columns and columns->rows), try the following little Perl script:
# Example CSV file # FROM: # a1,a2,a3 # b1,b2,b3 # TO: # a1,b1 # a2,b2 # a3,b3
perl -e'$unequal=0;$_=<>;s/\r?\n//;@out_rows=split(/\,/, $_);\
$num_out_rows=$#out_rows+1;while(<>){s/\r?\n//;@F=split(/\,/,$_);\
foreach $i(0 .. $#F){$out_rows[$i] .="\,$F[$i]";}if($num_out_rows !=$#F+1){\
$unequal=1;}}END{foreach $row (@out_rows){print"$row\n"}\
warn "\nWARNING! Rows in input had different numbers of columns\n" if $unequal;\
warn "\nTransposed table: result has $. columns and $num_out_rows rows\n\n"}' $1
