想要运行.sh Linux shell脚本来重命名文件

I would like to run a .sh script to rename a file which is in the directory desktop/reports/don of my computer. An example of what I need is to rename:

我想运行一个.sh脚本来重命名我的计算机目录desktop / reports / don中的文件。我需要的一个例子是重命名:

TACOS_2013-Jan-22__00-50-00_UTC.csv

TACOS_20130122_005000.csv

I have the following script which was created using windows batch script(.bat file). I would like to convert this into linux shell script.

我有以下脚本,它是使用Windows批处理脚本(.bat文件)创建的。我想将其转换为linux shell脚本。

@echo off
setlocal
for /f "tokens=2-7 delims=_.-" %%A in ('dir /B TACOS_*') do (
  setlocal enabledelayedexpansion
  call :getmonth %%B
  ren TACOS*_*%%A-%%B-%%C*_*%%D-%%E-%%F_UTC.csv TACOS_%%A!mon!%%C_%%D%%E%%F.csv
  endlocal
)


:getmonth
if "%1" equ "Jan" set mon=01
if "%1" equ "Feb" set mon=02
if "%1" equ "Mar" set mon=03
if "%1" equ "Apr" set mon=04
if "%1" equ "May" set mon=05
if "%1" equ "Jun" set mon=06
if "%1" equ "Jul" set mon=07
if "%1" equ "Aug" set mon=08
if "%1" equ "Sep" set mon=09
if "%1" equ "Oct" set mon=10
if "%1" equ "Nov" set mon=11
if "%1" equ "Dec" set mon=12
goto :eof
endlocal

this is what i have done so far..Please help

这就是我到目前为止所做的事情。请帮助

#!/bin/bash
month["Jan"]=01
month["Feb"]=02
month["Mar"]=03
month["Apr"]=04
month["May"]=05
month["Jun"]=06
month["Jul"]=07
month["Aug"]=08
month["Sep"]=09
month["Oct"]=10
month["Nov"]=11
month["Dec"]=12

directory="desktop/reports/Don/"
for path in "${directory}TACOS_"*; do

    path=${path#${directory}}
    newpath=${path:0:10}${month[${path:11:3}]}${path:15:2}
    newpath=${newpath}__$(tr -d '-' <<< ${path:19:8}).csv

    echo "${directory}${path}" "${directory}${newpath}" # Run this one first!!!
    # mv "YOUR/PATH/${path}" "YOUR/PATH/${newpath}"
done

Now that you made it a bit clearer, I guess this is what you want:

既然你让它更清晰一点,我想这就是你想要的:

an associative array to map "MONTH NAME" to "MONTH NUMBER";

一个关联数组,用于将“MONTH NAME”映射到“MONTH NUMBER”;

rename a file from "TACOS_YYYY-month-dd__HH-MM-SS*.csv" to "TACOS_YYYYmmdd_HHMMSS.csv".

将文件从“TACOS_YYYY-month-dd__HH-MM-SS * .csv”重命名为“TACOS_YYYYmmdd_HHMMSS.csv”。

The solution in a bash script:

bash脚本中的解决方案:

#!/bin/bash
declare -A month
month["Jan"]=01
month["Feb"]=02
month["Mar"]=03
month["Apr"]=04
month["May"]=05
month["Jun"]=06
month["Jul"]=07
month["Aug"]=08
month["Sep"]=09
month["Oct"]=10
month["Nov"]=11
month["Dec"]=12

directory="YOUR/PATH/TACOS_"
for path in "${directory}"*; do

    path=${path#${directory}}
    newpath=${path:0:4}${month[${path:5:3}]}${path:9:2}
    newpath=${newpath}__$(tr -d '-' <<< ${path:13:8}).csv

    echo "${directory}${path}" "${directory}${newpath}" # Run this one first!!!
    # mv "YOUR/PATH/${path}" "YOUR/PATH/${newpath}"

done

This converts the string path=TACOS_2013-Jan-22__00-50-00_UTC.csv into newpath=TACOS_20130122__005000.csv, and renames the initial file mv'ing it to the new path constructed.

这会将字符串路径= TACOS_2013-Jan-22__00-50-00_UTC.csv转换为newpath = TACOS_20130122__005000.csv,并将初始文件mv'重命名为构造的新路径。

As in explanation, bash offers you associative arrays, that you have to declare prior to any operation using declare -A assoc_array.

在解释中,bash为您提供了关联数组,您必须在使用declare -A assoc_array的任何操作之前声明这些数组。

In bash you can take string intervals, setting an offset, a length, and doing ${string:offset:length}. Concatenation is performed by juxtaposition of strings, and assignments must have no spaces between left_value=right_value.

在bash中,您可以获取字符串间隔,设置偏移量,长度以及执行$ {string:offset:length}。连接是通过并置字符串来执行的,并且赋值必须在left_value = right_value之间没有空格。

In addition, you have tr command, translating your string from initial to initial_without_characters, since the flag -d has been used. You may take a look at man tr for further reference.

此外,您还有tr命令,将字符串从initial翻译为initial_without_characters,因为已使用标志-d。您可以查看man tr以获得进一步的参考。

Edit:

Since you don't have a more recent version of bash, you can use the following code:

由于您没有更新版本的bash,因此可以使用以下代码:

#!/bin/bash
function month() {

    case $1 in
        "Jan") echo "01" ;;
        "Feb") echo "02" ;;
        "Mar") echo "03" ;;
        "Apr") echo "04" ;;
        "May") echo "05" ;;
        "Jun") echo "06" ;;
        "Jul") echo "07" ;;
        "Aug") echo "08" ;;
        "Sep") echo "09" ;;
        "Oct") echo "10" ;;
        "Nov") echo "11" ;;
        "Dec") echo "12" ;;
    esac

}

directory="YOUR/PATH/TACOS_"
for path in "${directory}"*; do

    path=${path#${directory}}
    newpath=${path:0:4}$(month ${path:5:3})${path:9:2}
    newpath=${newpath}__$(tr -d '-' <<< ${path:13:8}).csv

    echo "${directory}${path}" "${directory}${newpath}" # Run this one first!!!
    # mv "YOUR/PATH/${path}" "YOUR/PATH/${newpath}"

done
