Bash 腳本可以在提示符下工作，但不能在 cron 下工作

從 cron 執行 bash 腳本時失敗並出現以下錯誤

/bin/sh: -c: line 0: unexpected EOF while looking for matching ``'
/bin/sh: -c: line 1: syntax error: unexpected end of file

奇怪的是從提示符執行時它可以完美執行

整個腳本

#!/bin/sh
NOW=$(date +"%b-%d-%y")
bu_PATH="/home/webserver/"

curtime=$(date)

echo ""
echo "Starting backup: $curtime"
echo ""
echo "Moving to $bu_PATH"
cd $bu_PATH

BACKUP_FILE="backup_$NOW.tgz"

echo ""
echo "The backup file will be called $BACKUP_FILE"

RUN_BACKUP="/usr/local/psa/bin/pleskbackup --server --output-file=$bu_PATH$BACKUP_FILE"

echo "Running backup...."
echo `$RUN_BACKUP`

curtime=$(date)

echo "Backup complete: $curtime"

echo ""

echo "Remove older than 7 days of files..."
ssh server '/shares/backup/webserver/cleanup.sh'

curtime=$(date)
echo ""

echo "Connecting to FTP: $curtime"

sftp -b server <<EOF
       cd /shares/backup/webserver/
       put $bu_PATH$BACKUP_FILE
       quit
EOF;

curtime=$(date)
echo "FTP Transfer Complete: $curtime"
echo ""
echo "Cleaning up Local backups"
sh /home/cleanup.sh
echo ""
echo "Clean up log files"
find /home/webserver/logs/*.log -mtime +7 -exec rm {} \;
echo "Job Complete"

這是 crontab 條目

/home/backup.sh > /home/webserver/logs/BackupLog-`date +%m%d%y`.log

謝謝羅伯

如果在 crontab 中使用反引號 (`)，則需要轉義 crontab 條目中的 % 符號。

像這樣：

/home/backup.sh > /home/webserver/logs/BackupLog-`date +\%m\%d\%y`.log

如果您不逃避它們，它們將被視為換行符。

你的 EOF 看起來不對，EOF；與您預期的 EOF 不匹配（刪除分號）。

[hlinden@dolphin tmp]$ cat dog.sh
#!/bin/bash
貓 <<EOF
狗
貓
EOF;
[hlinden@dolphin tmp]$ sh dog.sh
dog.sh：第 6 行：警告：第 3 行的此處文件由文件結尾分隔（需要“EOF”）
狗
貓
EOF;
[hlinden@dolphin tmp]$ sed -is/\;// dog.sh
[hlinden@dolphin tmp]$ sh dog.sh
狗
貓
[hlinden@dolphin tmp]$
