Shell Programming and Scripting

hi all,

i have a file that contains the following kind of data

codeexpert_package_module1.html
codeexpert_package_module2.html
codeexpert_package_module3_revision2.html
and it goes on ..

i need to get the following data from it
package_module1
package_module2

i know basename command can be used to remove ".html" part but how to cut the data till the first occurance of the "_".

Try this:

Code:

 
cat file_name | while read line
do
  echo ${line} | cut -d '_' -f2,3 | cut -d '.' -f1 >> /tmp/test.txt
done

cat tmp/test.txt

HTH,

Regards,

Praveen

Code:

 
echo "codeexpert_package_module3_revision2.html" | awk -F"." '{print $1}' | awk -F"_" '{  print $2"_"$3 }'

Code:

echo 'codeexpert_package_module3_revision2.html' | sed 's/^[^_][^_]*_\(.*\)[.][^.][^.]*$/\1/'
