Shell Programming and Scripting

Hi All,
Would like to ask on how to refrain the message file not exists from display out.


    if [ `ls ${src}_*/*.CTL |awk '{print $1}'|wc -l ` -gt 0 ]; then

    

When it execute, the OS will throw the error file does not exists 

    ls: 0653-341 The file COL_*/*.CTL does not exist.

Thanks.

The file you are trying to list does not exist

if ls ${src}_*/*.CTL &> /dev/null; then 
     echo "yes files are there"
else 
     echo "No files"
fi

Try:

if [ $(ls ${src}_*/*.CTL  2>/dev/null|wc -l) -gt 0 ]; then

or:

if ls ${src}_*/*.CTL >/dev/null 2>&1; then

 2>/dev/null
