How to find yesterdays file - shell script
Hey guys - i have a script (below) that searches for current files in a particular directory.

However i was wondering how to make it search for "yesterdays" file. For instance it looks for a file from yesterday and no older than that.

I used stat command to check for file information:


Code:
function checkStat

{

    # make sure stat command is installed

    which stat > /dev/null 2>&1

    if [ $? -eq 1 ]; then
        echo "stat command not found!"
        exit 2
    fi

}



function processFile

{

    if [ -s ${1} ]; then
        VAR="$(stat -c %y ${1})"
        VAR2="${VAR:0:10}"

        FILE_TIME=$(ls -l $1| cut -d" " -f6,7,8,9)
        FILE_SIZE=$(du -sh $1 | cut -f1)
        if [ $NOW == $VAR2 ]; then
            echo "Current File Found: ${1} DATED $FILE_TIME - SIZE $FILE_SIZE" | tee -a ${CURRENT_FILE}
        else
            erroremail=1
            echo "Outdated File Found: ${1} DATED $FILE_TIME - SIZE $FILE_SIZE" | tee -a ${OLD_FILE}
        fi

    else
        erroremail=1
        echo "File Not Found OR 0KB in SIZE: ${1}" | tee -a ${FILE_NOT_FOUND}
    fi



}

    for f in ${FILE[@]}; do

    done
done

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
