bash验证文件类型的完整性并创建日志

我正在尝试使用bash来验证特定下载.bam文件的完整性。有两个部分(bash 1)运行命令来验证创建.bam文件的.txt文件,并创建process.log。该部分工作正常,我收到错误的是检查每个.txt文件中的字符串(SUCCESS),如果找到它,那么在process.log该文件被验证,如果它找不到那个文件已损坏。目前,终端显示状态,然后给出错误。谢谢你:)。

bash第1部分

logfile=/home/cmccabe/Desktop/NGS/API/5-4-2016/process.log
for f in /home/cmccabe/Desktop/NGS/API/5-4-2016/*.bam ; do
 echo "Start bam validation creation: $(date) - File: $f"
 bname=`basename $f`
 pref=${bname%%.bam}
 bam validate --in $f --verbose 2> /home/cmccabe/Desktop/NGS/API/5-4-2016/bam_validation/${pref}_validation.txt
 echo "End bam validation creation: $(date) - File: $f"
done >> "$logfile"
 echo "Start verifying $(date) - File: $file"
 value=$( grep -ic "(SUCCESS)" /home/cmccabe/Desktop/NGS/API/5-4-2016/bam_validation/*.txt )

bash第2部分

 if [ $value -eq 1 ]
 then
 echo "bam file is verified and complete"
 else
 echo "bam is corrupt, check log for reason"
 echo "End bam verify: $(date) - File: $f"
 fi
 done >> "$logfile"

答案 0 :(得分:1)

错误是由于最简单的原因,bash如果你使用单个括号[]来评估一个条件,它只不过是隐含的使用bash {{1}的方法。 } expression,它将test扩展为包含空格的字符串,将特殊字符作为单独的参数。在这里你留下了变量模糊,可以扩展到一些错误情况下的多个参数。

您需要做的就是将该变量括在双引号中,以便将其视为一个单独的字符串。
