Question Splitting fixed length file using awk
Hi,
I need to split a fixed length file of 160 characters based on value of a column. Example:
Code:
ABC   456780001 DGDG SDFSF
BCD   444440002 SSSS TTTTT
ABC   777750003 HHHH UUUUU
THH   888880001 FFFF  LLLLLL
HHH   999990002 GGGG OOOOO

I need to split this file on basis of column from position 12-15 i.e 0001,0002,0003 and copy the data to files 0001.txt,0002.txt,0003.txt.

so 0001.txt should contain
Code:
ABC   456780001 DGDG SDFSF
THH   888880001 FFFF  LLLLLL

002.txt should contain
Code:
BCD   444440002 SSSS TTTTT
HHH   999990002 GGGG OOOOO

003.txt should contain
Code:
ABC   777750003 HHHH UUUUU

and all the new files should have same fixed width as the original file.

Kindly help how can i achieve this.Smilie

Question Splitting fixed length file using awk
Thanks Yoda. It is working fine.

Can you also tell me how can i append the file name with a parameter. Something like 0001_RL_$1.txt. $1 being passed as an arguement.

or else if $1 can be picked up from file itself from position 60-64.

stealing Yoda's code:
Code:
awk '{F=substr($0,12,4) "_RL_" substr($0,60,5) ".txt"; print $0 >> F; close(F) }' file

Hi,
I am facing one issue here. The command works fine if i hardcode the file name but if is pass it as an arguement it doesn't work. For e.g:Below commands works fine
Code:
awk -v A="$type" '{F=substr($0,23,8) "_LTD_" A ".txt"; print $0 >> F; close(F) }' RL004.txt

But the below command does not work.
Code:
awk -v A="$type" '{F=substr($0,23,8) "_LTD_" A ".txt"; print $0 >> F; close(F) }' $path/$filename

Can you please help with this.
