Hi,

Can you please let me know how to search records in a file which are greater than length 1000.

Thanks,
Anil

In ksh, ${#parameter} is the length of parameter:

#!/bin/ksh

while read line
do
if [[ ${#line} > 1000 ]]
then
echo ${line}
fi
done < myfile

Hi,

The above code displays all the records in the file - even though their length is less than 1000.

Do I have to specify anything in the place of #

Thanks,
Anil

I don't know what to tell you; it works for me just the way it is written. Are you sure you are using ksh.

You can use the expr command to also get the length:

#!/bin/ksh

while read line
do

if [[ $(expr "${line}" : '.*') > 1000 ]]
then
echo ${line}
fi
done < myfile

The first solution works for me on HP-UX only if I use -gt or -ge. Also, you will want to set IFS to null to prevent echo from collapsing any amount of white space to single spaces - in other words, to preserve your line exactly as it is.

#!/bin/ksh

IFS=

while read line
do
if [[ ${#line} -gt 9 ]]
then
echo ${line}
fi
done < myfile
