nawk -f alpesh.awk OFS='\t' myFile
alpesh.awk:

This will be some work and it is going to become complex. Let us address one problem after the other. I suggest to use sed for this sort of text manipulating tasks.

The general way of addressing...

$ cat abstract.awk

BEGIN { OFS="\t" }

/^[0-9]+[ \t]*$/ {
if(T) print T, A[1], A[2], ASTR, ABSTR;
getline T
}

/^Pages/ {
split($2, A, "-");

With your sample of 6 cols, try:
awk 'gsub(FS $3,"&")<4' infile | sort -k2,2n -k1,1
(So 4 should be 230 for 232 cols..)

Loop increment is missing there, so that the infinite loop occurs. I posted through mobile, something went wrong... Sorry for the inconvenience:-)

You need to set the output delimiter to TAB as well (FS=OFS="\t")

Hi,

Try this one,

cd path
for file in *
do
awk 'BEGIN{FS=":";}{$2="chr"$2;a[NR]=$0;}END{for(i=1;i<=NR;i ){print a[i] >FILENAME;}}' ${file}
done

It is quite difficult to work from faulty code (syntax error on line 1).
Please post sample before and after data and explain the process in more detail.

This code below should take care of this:

awk 'NR == FNR {
c = x
while (match($6, /[0-9]*[SM]/)) {
p1 = substr($6, RSTART + RLENGTH - 1, 1)
p1 == "M" && !c++ && t[$1, "S"]++
...

tr -d '\015' < myFile > myNewFile

Yes, this should do the trick:

perl -i -pe's/\r\n/\n/g' file2_truncated.txt file1_truncated.txt

1. Execute dos2unix file2_truncated.txt file1_truncated.txt.
2. Try this and check the result:

awk 'NR == FNR {
f2[$1] = $10; next
}
$4 in f2 {
print $0, substr(f2[$4], $8 - $2 , $9 -...

This is what I get with your files:

awk 'NR == FNR {
f2[$1] = $2; next
}
$1 in f2 {
print $0, substr(f2[$1], $3 - $2, $4 - $3)
}' file2 file1% awk 'NR == FNR {
f2[$1] = $2; next
...

I'm not sure if 'START' position really matters - you're extracting from POS1 to POS2 anyway. Or are POS1 and POS2 relative to the START?
something along these lines - debug with a sample file1:
