Shell Programming and Scripting

try:

Code:

awk -v RS=">" -v FS="\n" '{printf $1"\t";for(i=2;i<=NF;i++) printf $i;print ""}' fasta

I am not getting the expected output file.
What I need is to combine these 2 awk codes into one

Code:

awk '$1=substr($1"       ",1,8)"  "' FS="\n" OFS= RS=\> file

Code:

awk '{s=length($2)}END{print NR-1, s}' file

The first one is getting the SeqIDs and the sequences but it does not list in the first line the number of sequences or the length.
The second one takes care of the number of sequences and the length but it does not output the IDs and sequences.
I would like to modify the first code so it can include the number of sequences and length in the very first line.
Thanks!

Code:

awk '$1=substr($1"       ",1,8)"  "' FS="\n" OFS= RS=\> fastafile |awk 'NF>0{s=length($2);t=t"\n"$0}END{print NR-1,s"\n"t}'

I only had to remove "\n" to get the rigth format.
Thank you very, very much!

The code seems to have some issues when the Sequence IDs are shorter than 8 characters. I have uploaded the corresponding input and output files.

Try:
^M is Ctrl+V+M

Code:

sed '$!N;s/^M\n/\t/;s/>//' input|awk '{s=length($2);t==0?t=$0:t=t"\n"$0}END{print NR,s"\n" t}' output

It works great on CygWin and VirtualBox but not on my Linux box (redhat)
