help needed for awk
Dear all,

I am new to use unix. I run the following command and got the error. Anyone knows how should I modify the command. Thanks a lot!

$
Code:
for chr in 'seq 1 23'; 
  do 
  awk 'BEGIN {print "T","pheno";}{print "M",$2}' out_${chr}.map > dat_${chr}.dat;
  done
 
error message: -bash: dat_${chr}.dat: ambiguous redirect

one-liners like that are harder to debug - consider opening them up.

start by changing
Code:
for chr in 'seq 1 23'; 
# to
for chr in $(seq 1 23 )
