Shell Programming and Scripting

HI,

I am pretty new to Unix scripting. I will need help in Finding a character in first line of a file or a set of files.

The scenario is as follows:

Lets consider a set of files which is having a character "ID"(without quotes) in the first line of each file.I need to find this character in the first line of each file and if the result of this is positive then i have to say echo"ID found in file" otherwise echo "ID not found in the file"

Can anyone help me with this. I will be very Gratefull

Thanks,
Sandy

is it homework? if so, have a look at the rules!

NO!!!! this is not a home work.......

I have tried searching this through google from past three days.....but i am not able to find any answers on this.......can anyone help me out ...

Thanks,
Sandy

Perhaps this.

Code:

while read filename
do
  line=$(head -1 $filename)
  if [[ $line = *ID* ]] ; then
    echo "Found ID in $filename"
  else
    echo "No ID in $filename"
  fi;
done < list_of_filenames.txt

Code:

awk 'NR==1{ if ( $0 ~ /ID/) print }' "file"

Thanks so much.....u guys are awesome.......i hope that i am also as good as u guys and help someone in this forum in the comming months.

Thanks and regards,
Sandy
