Help with text modification and displaying
I have a file storing some text
and another file storing some numbers
I want to display characters other than the specified place of strings


one.txt
Code:
xyz abc 233 skfo 4r443
sfs abc abcd sd fsdf  sdfd 
abc 11 abc 33 abc dsaf

two.txt
Code:
Nt_djd_k='5-6,7-9'
Nt_hh_l='3-6,7-8'

Code:
a=`grep 'Nt_djd_k' two.txt | cut -d "=" -f2 | sed "s/'//g"`

echo $a

cut -c$a one.txt

o/p:
Code:
abc 2
abc a
11 ab

o/p required:
Code:
xyz 33 skfo 4r443
sfs bcd sd fsdf  sdfd

Please use code tags as required by forum rules!

Does your cut provide the --complement option?
Code:
cut -c$a --complement one.txt
xyz 33 skfo 4r443
sfs bcd sd fsdf sdfd
abc c 33 abc dsaf

I am getting this error
Code:
echo "ABCD" | cut -c2 --complement
cut: Not a recognized flag: -
Usage: cut -b List [-n] [File...]
   or: cut -c List [File...]
   or: cut -f List [-d Character] [-s] [File...]

In my system cut doesn't support --complement

Help me with any other option

Hello rahulsk,

Following may help you in same, here I am considering that your two.txt file may help more than 2 lines.
Code:
awk 'FNR==NR{match($0,/\=.*/);A[++i]=substr($0,RSTART+2,RLENGTH-3);sub(/\,/,"-",A[i]);next} {if(FNR%2==0){q=FNR>i?i:FNR;{split(A[q], Y,"-");C=substr($0,1,Y[1]-1);if(Y[2]==Y[3]-1){print C OFS substr($0,Y[4]+1)} else {C=C OFS substr(B,Y[2]+1,Y[3]-Y[2]-1);;C=C OFS substr($0,Y[4]);print C;C="";}}}} {if(FNR%2!=0){q=FNR>i?i:FNR;{split(A[q], Y,"-");C=substr($0,1,Y[1]-1);if(Y[2]==Y[3]-1){print C OFS substr($0,Y[4]+1)} else {C=C OFS substr(B,Y[2]+1,Y[3]-Y[2]-1);;C=C OFS substr($0,Y[4]);print C;C="";}}}}' two.txt one.txt

Output will be as follows.
Code:
xyz  33 skfo 4r443
sf abcd sd fsdf  sdfd
ab bc 33 abc dsaf

Also here I want to mention that lets say there are 2 lines(as your shown Input_file) in two.txt file then 1st line rule(to cut the strings from 5-6,7-9) will be applied to all lines in one.txt which are not divided by 2 means all odd lines of one.txt and similarly 2nd line of two.txt rule (to cut the strings from 3-6,7-8) will be applied to all line of one.txt's all even lines, also considering that your two.txt file has only 2 conditions like (5-6,7-9)always, let me know if this helps you.


EDIT: Adding a non-one liner for of solution on same.
Code:
awk 'FNR==NR{
                match($0,/\=.*/);
                A[++i]=substr($0,RSTART+2,RLENGTH-3);
                sub(/\,/,"-",A[i]);
                next
            }
            {
                if(FNR%2==0){
                                q=FNR>i?i:FNR;{ B=$0
                                                split(A[q], Y,"-");
                                                C=substr($0,1,Y[1]-1);

                                                                }
