Shell Programming and Scripting

Thanks for all your help n effort...Just 1 flaw.. plzz help $ lsCFG.txt mXZ.txtTWE.txt ekr.txt test after running the ls command 4 files are created.I do not want the file to be created for last line i.e ekr.txt is unwanted file which should not be created as it is last line and hence no need to process it

make sure you dont have any blank line in your main file

do

Code:

cat -n filename

if you have the last line as empty, then the provided awk command will create the file called ekr.txt

it is not flaw, it is the problem with your input file

Thanks a ton I got my mistake
All working fine.....

Need 1 more favor!!!

I need to write shell script for same which will read input file i.e test from particular location n then will execute awk command on same.

Help me with same.

May be it may sound too basic... but i'm beginner in Unix

which will read input file i.e test from particular location

will the filename change everyday ?
how the filename looks like ?

Code:

 
filename="/tmp/test"
lineno=`wc -l < $filename`
nawk -v lineno="$lineno" '{ if (NR>1 && NR < lineno){f=substr($1,length($1)-2)".txt";print >> f;close(f)}}' $filename

Yes the filename will change but it will be placed at one location.

Nothing specific format for filename.

then pass the filename as argment to your script. and read using $1

Code:

filename=$1
