如何通过Shell脚本检查文件名格式?

问题描述

你好，

我编写了一个shell脚本，该脚本接受输入文件作为cmd行参数并处理该文件.

Hello,

I had written a shell script that accepts input file as cmd line argument and process this file.

if [ $# -eq 1 ]; then
 if [ -f $1 ]; then
   . $1
   LOGFILE="$LOG_FILE/MIG_BIOS.log";
    get_input_file

 else
  ERROR_CODE=MSCRM0005_003
  error "$ERROR_CODE : Input file $1 is not available";
  exit 1
 fi

else
 echo "usage : $usage";
fi

我需要帮助来编写用于检查文件名格式的get_input_file函数.
我的输入文件名格式是MIG_CR_< TYPE> _< TIMESTAMP>.< EXT>

I want a help in writting a get_input_file function which checks for file name format.
My input file name format is MIG_CR_<TYPE>_<TIMESTAMP>.<EXT>

get_input_file()
{
FILE = ''$1''
# checking file exist or not
if [ ! -f $FILE ]; then
    echo "$FILE : does not exists";
    exit 1
elif [ ! -r $FILE ]; then
    echo "$FILE: can not read";
    exit 2
fi

// TO do
// check file name foramt is correct or not
}

谁能告诉我如何检查文件名的格式?
请帮帮我.

Can anyone tell me how can I check the format of file name?
Please help me out. Thanks in advance.
