需要有关以下 korn shell 的帮助。语句 if (( ${lista[expr $FNO + 5]} == $MM ));
因语法错误而失败。获取 == 的语法错误。也试过 -eq 但同样的问题。
这不会返回任何内容:${lista[expr $FNO + 5]}
。
如何在这里获取月份值?
#!/bin/ksh
# get a list of files and dates from ftp and remove files older than ndays
ftpsite="xxx.com"
ftpuser="ftpuser"
ftppass="ftppwd"
putdir="/ftpdir"
MM=`TZ=GMT+29 date +%b`
DD=`TZ=GMT+29 date +%d`
echo removing files older than $MM $DD
# get directory listing from remote source
listing=`ftp -i -n $ftpsite <<EOMYF
user $ftpuser $ftppass
binary
cd $putdir
ls -l
quit
EOMYF`
lista=$listing
# loop over our files
FNO=0
while (( $FNO < ${#lista[@]} )); do
# month (element 5), day (element 6) and filename (element 8)
#echo Date ${lista[`expr $FNO+5`]} ${lista[`expr $FNO+6`]} File: ${lista[`expr $FNO+8`]}
# check the date stamp
if (( "${lista[`expr $FNO + 5`]}" == $MM ));
then
if (("${lista[`expr $FNO + 6`]}" -lt $DD ));
then
# Remove this file
echo "Removing ${lista[`expr $FNO + 8`]}"
echo "Removing ${lista[`expr $FNO + 8`]}"
ftp -i -n $ftpsite <<EOMYF2
user $ftpuser $ftppass
binary
cd $putdir
delete ${lista[`expr $FNO+8`]}
quit
EOMYF2
fi
fi
(( FNO = $FNO + 9 ))
done
请为此寻求帮助。
谢谢你试图帮助我。是的,我从 pastebin 本身复制了它。当我尝试使用 ls *.txt 获得如下输出时,它没有获得 5 美元的值(value),因此,根据您的建议尝试 ls -l *.txt。我还能尝试什么?
- 设置--ccc_20160301.txt
- (( 1 > 9 ))
- [[ == 二月 ]]
- 读行
下面是我从 pastebin 本身复制的脚本
#!/bin/ksh -px
# get a list of files and dates from ftp and remove files older than ndays
ftpsite="ftp.com"
ftpuser="ftpuser"
ftppass="ftppass"
putdir="/xxx/yyy"
MM=$(TZ=GMT+29 date +%b)
DD=$(TZ=GMT+29 date +%d)
echo "removing files older than $MM $DD"
# get directory listing from remote source
echo "
user $ftpuser $ftppass
binary
cd $putdir
ls *.txt
quit" | ftp -i -n $ftpsite | while read line; do
# line is *each line*, rather than a list of everything
# helps if the filenames have spaces. Just chomp into $0..
set -- $line
# month (element 5), day (element 6) and filename (element 8)
if (($# > 9)); then
echo "Can't deal with '$@'"
continue
fi
# check the date stamp
if [[ $5 == "$MM" ]];
then
if (($6 < $DD ));
then
# Remove this file
filename=$8
echo "Removing $filename"
# replace the ftp with cat with ftp $ftpsite
cat <<EOMYF2
ftp -n -i $ftpsite
user $ftpuser $ftppass
binary
cd $putdir
delete $filename
quit
EOMYF2
fi
fi
done
最佳答案
当您分配:lista=$listing
时,这是一个简单的变量分配。
您想将 listing
作为数组分配给 lista
。语法是:
set -A lista $listing
BTW, I'd use
$()
instead of backticks for command invocation, and use$((math))
instead ofexpr math
, as they're more ksh-fluent.
尝试调试文件的 ftp 列表:
ftpsite="xxx.com"
ftpuser="ftpuser"
ftppass="ftppwd"
putdir="/ftpdir"
ftp -i -n $ftpsite <<EOM
user $ftpuser $ftppass
binary
cd $putdir
ls -l *.txt
quit
EOM
这将列出所有考虑的文件 - 您需要确保它们都具有相同的格式。
一旦您确保格式符合预期的每行 9 个项目,您就可以尝试调试脚本。
