我在shell脚本中运行awk命令,它正在破坏数据文件。所有数据都没有加载,并且每行末尾都有换行符。
awk -v name="$filename" -v batch="$BATCHNAME" -F'|' 'BEGIN{OFS="|"}{$2=batch;print > (name".locked.concur")}' $filename.locked.concur
如果我将其作为命令运行,它就能完美运行。
我刚刚发现我可以使用fflush(),它似乎已经解决了这个问题。
所以现在我有:
awk -v name="$filename" -v batch="$BATCHNAME" -F'|' 'BEGIN{OFS="|"}{$2=batch;print > (name".locked.concur") fflush()}' $filename.locked.concur
我是否为灾难做好准备?
此外,该文件被重命名为$ filename.locked.concur0 - 我猜这个零是从fflush返回的退出代码?我如何摆脱这个0?
完整代码:
for filename in `cat ${INFILEDIR}/file_list_concur`
do
rm -f $OHAP_DAT/bad/$filename.bad
##Create Batchname based on filename
BATCH_GROUP=`ls $filename.locked.concur |cut -d '_' -f 1`
BATCH_DATE=`ls $filename.locked.concur |cut -d '_' -f 2`
BATCHNAME=${BATCH_GROUP}_Concur_${BATCH_DATE}
echo 'Batch Date = '$BATCH_DATE
echo 'Batch Group = '$BATCH_GROUP
echo 'Batch Name = '$BATCHNAME
echo 'File Name = ' $filename
gawk -v name="$filename" -v batch="$BATCHNAME" -F'|' 'BEGIN{OFS="|"}{$2=batch;print > (name".locked.concur");}' $filename.locked.concur
##End Batchname
sqlldr $ORACLE_PW control=$XXOH_TOP/bin/XXOH_AP_CONCUR_IMPORT_CTL.ctl \
data=$OHAP_DAT/in/$filename.locked.concur \
log=$OHAP_DAT/log/$filename.log \
bad=$OHAP_DAT/bad/$filename.bad \
bindsize=512000 << end_of_sqlldr
end_of_sqlldr
if [ -f $OHAP_DAT/bad/$filename.bad ]
then
echo \!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
echo \!! 'date'
echo \!! SQL*Loader bad file was found!!
echo \!! Script $filename Failed - BAD FILE!
echo \!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
答案 0 :(得分:1)
问题确实是您正在读取和写入同一个文件。这应该会更好:
gawk ... print > (name".locked.concur.tmp")}' $filename.locked.concur
mv -f $filename.locked.concur.tmp $filename.locked.concur
更好的是:
gawk ... print}' $filename.locked.concur > $filename.locked.concur.tmp
mv -f $filename.locked.concur.tmp $filename.locked.concur
