how to fix the column length in a file using Awk Prog
Hi

I use the following code to read the file and to fix the length of the column of the record in the file 'Sample.txt'

Code:
ls Samp* | awk '
{ a[NR]=$1 }
END{
FS="n"
for(i=1;i<=NR;i++)
{
while( getline < a[i] ) 
{
f1=$0;
print("Line::",f1); 
f2=substr(f1,1,10) 
print("Field1::",f2);
f3=substr(f1,11,57)
print("Field2::",f3);
f5=substr(f1,58,75)
print("Field4::",f5);
f6=substr(f1,86,96) 
print("Field5::",f6);
f7=substr(f1,97,104)
print("Field6::",f7);
}
}

Contents of Sample.txt

Code:
1234567891XYZABC                            13/08/09 00:00:00 67890   12345 67890       00

but only field1 is printed correctly as below

Code:
Line::1234567891XYZABC                            13/08/09 00:00:00 67890   12345 67890       00

To keep the forums high quality for all users, please take the time to format your posts correctly.
  1. Use Code Tags when you post any code or data samples so others can easily read your code.
    You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
  2. Avoid adding color or different fonts and font size to your posts.
    Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
  3. Be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Remember, you have to use [code] tags when you post sample data and required output.
