Hi All.
Pls help me with the command to check existence of files (I'll mention name of the file as regex) and proceed with my further processing if atleast one of them exists

in detail,
I've a dir /tmp/TURP, which may or may not have files named with "exter*.txt"

I need to check and proceed if atleast one of these files exists in this dir.

Thanks in advance.

name="exter*.txt"

ls -l $name > /dev/null
 
if [ "$?" -eq "0" ]
then
     echo "Do your work here"
else
     echo "No files are there for the given pattern"
fi

same with little compact ..

if [ `ls /tmp/TURP/exter*.txt > /dev/null ; echo $?` -eq 0 ]; then echo "Files are there \n" ; else echo "Files not present \n"; fi
