Script modification

[djfog]

I have this script:

#!/bin/bash
while [ $1 ] ; do
lines=$(wc -l $1 | awk '{print $1}')
if [ $lines -ge 10 ]  ;  then
echo " $1 has $lines lines"
cat $1
else
echo " $1 has less than 10 lines"
fi
shift
done

That checks if a file has more than 10 lines and if so prints its content else it prints that it has less than 10 lines.What I want is the script to ask which file to check(using echo probably) so that the terminal execution will be like that

./script

and not

./script file_name

Thanks in advance for your advices.

Well,I must be an idiot not to find the similarity.Thanks for yr advice.I have this script now:

#!/bin/bash
read -p "enter the name of the file: " NAME
lines=$(wc -l $NAME | awk '{print $1}')
if [ "$lines" -ge "10" ]  ;  then
echo "$NAME has $lines lines"
cat $NAME
else
echo "$NAME has less than 10 lines"
fi

It's working like a charm...

you can use

wc -l < $FILE

to get just the count. No need for extra awk.

[ `wc -l < file` -gt 10 ] && echo "greater than 10" || echo "less than 10"

Thanks.Quite interesting.I'll keep that in mind for future scripts.
