Проблема с подключением WSL VPN

Просто ради интереса я бы сделал это, включив некоторое форматирование, чтобы облегчить чтение результирующего файла.

    #!/bin/ksh

    # This is just for formatting

    typeset -L15 Col1
    typeset -L15 Col2
    typeset -L50 Col3

    # Shouldn't use backtick, it's more or less deprecated by now
    EXT=$(date +"%Y%m%d")
    p_FP=${gp_LOAD_DIR}Client/

    cd ${p_FP}
    ###################################################
    # Create MD5_<<Process Date>>.txt File
    ###################################################

    # Just for speed. Since you are already using cksum for each line, it could be faster to avoid reopening the result file each time also

    exec 3>MD5_${EXT}.txt

    # Using ksh, you should use "print" instead of echo since it's builtin instead of external (faster)
    print -u 3 "MD5 CHECKSUM Roster for " ${EXT}

    Col1="MD5"
    Col2="File Size"
    Col3="FileName"

    print -u 3 "$Col1$Col2$Col3"

    for file in $p_FP*; do
        # cksum won't work on directories nor on names pipe
         if [[ -f $file && ! -p $file && $file != MD5_${EXT}.txt ]]; then
            # Again, that's just for formatting
            line=( $(cksum $file) )
            Col1=${line[0]}
            Col2=${line[1]}
            Col3=${line[2]}
            print -u 3 "$Col1$Col2$Col3"
         fi
    done

    # Closing the file

    exec 3>&-
