如何从定义时间测试输出的目录的变量中删除尾部斜杠

  • 772

Ubuntu 16.04

即使 for 的输出client in */; do不会产生斜杠，如果我在循环内对文件执行时间测试时回显变量 $client ，也会出现斜杠。

cd "$wDir"
for client in */; do
   cd "$wDir"/"$client";

   #-- check to see if any .csv files exists
   if ls *.csv &>/dev/null; then
      for csvfile in *.csv; do
         if test $(find "$csvfile" -mmin +2880); then
            echo "$client has files older than 2 days ..." >> "staleFtpAccts"
         fi
      done
   fi
done

当我执行脚本时，在 $client 变量之后放置一个 / ，如下所示：

root@me /home/frank # bash script.sh
Start ...
000029_000020/ has files older than 2 days ...
#--
Finished ...

Start ...
000033_000040/ has files older than 2 days ...
#--
Finished ...

Start ...
000033_000041/ has files older than 2 days ...
#--
Finished ...

Start ...
000033_000042/ has files older than 2 days ...
#--
Finished ...

Start ...
000033_000043/ has files older than 2 days ...
#--
Finished ...

这是我追求的结果...

root@me /home/frank # bash script.sh
Start ...
000029_000020 has files older than 2 days ...
#--
Finished ...

Start ...
000033_000040 has files older than 2 days ...
#--
Finished ...

Start ...
000033_000041 has files older than 2 days ...
#--
Finished ...

Start ...
000033_000042 has files older than 2 days ...
#--
Finished ...

Start ...
000033_000043 has files older than 2 days ...
#--
Finished ...
bash delete

    试试这个 参数扩展：

    echo "${client%/}"

    所以

    echo "${client%/} has files older than 2 days ..."

    参数扩展扩展参数："$foo", "$1". 您可以使用它来执行字符串或数组操作："${file%.mp3}", "${0##*/}", "${files[@]: -4}". 他们应该总是被引用。请参阅： http: //mywiki.wooledge.org/BashFAQ/073和 man bash 中的“参数扩展”。另请参阅http://wiki.bash-hackers.org/syntax/pe。
