我的剧本的第一部分作品在Debian喘息框：AWK Debian的挤压与Debian的喘息
OUTPUT_DIR=/share/es-ops/Build_Farm_Reports/WorkSpace_Reports
BASE=/export/ws
TODAY=`date +"%m-%d-%y"`
HOSTNAME=`hostname`
WORKSPACES=("bob_avail" "bob_used" "mel_avail" "mel_used" "sideshow-ws2_avail" "sideshow-ws2_used")
if ! [ -f $OUTPUT_DIR/$HOSTNAME.csv ] && [ $HOSTNAME == "sideshow" ]; then
echo "$HOSTNAME" > $OUTPUT_DIR/$HOSTNAME.csv # with a linebreak
separator="," # defined empty for the first value
for v in "${WORKSPACES[@]}"
do
echo -n "$separator$v" >> $OUTPUT_DIR/$HOSTNAME.csv # append, concatenated, the separator and the value to the file
#separator="," # comma for the next values
done
echo >> $OUTPUT_DIR/$HOSTNAME.csv # add a linebreak (if you want it)
WORKSPACES2=("bob" "mel" "sideshow-ws2")
df -m "${WORKSPACES2[@]/#//export/ws/}" | awk '
BEGIN { "date +'%m-%d-%y'" | getline date;
printf "%s",date }
NR > 1 { printf ",%s,%s", $3, $2; }
END { printf "\n"}' >> "$OUTPUT_DIR/$HOSTNAME.csv"
elif [ $OUTPUT_DIR/$HOSTNAME.csv ] && [ $HOSTNAME == "sideshow" ]; then
WORKSPACES2=("bob" "mel" "sideshow-ws2")
df -m "${WORKSPACES2[@]/#//export/ws/}" | awk '
BEGIN { "date +'%m-%d-%y'" | getline date;
printf "%s",date }
NR > 1 { printf ",%s,%s", $3, $2; }
END { printf "\n"}' >> "$OUTPUT_DIR/$HOSTNAME.csv"
else
:
fi
，并产生这样的日产量每个cron的上午3:00 -8GMT熄灭时间：
sideshow
,bob_avail,bob_used,mel_avail,mel_used,sideshow-ws2_avail,sideshow-ws2_used
09-20-14,470400,1032124,661826,1032124,43443,8
09-20-15,470400,1032124,661826,1032124,43443,8
09-20-16,470400,1032124,661826,1032124,43443,8
但由于某些原因，当我尝试在这些其他3 Debian的挤压盒中运行它，我得到的值之间的三重逗号：
case "$HOSTNAME" in
simpsons) WORKSPACES=(bart_avail bart_used homer_avail home_used lisa_avail lisa_used \
marge_avail marge_used releases_avail releases_used rt-private_avail rt-private_used \
simpsons-ws0_avail simpsons-ws0_used simpsons-ws1_avail simpsons-ws1_used simpsons-ws2_avail \
simpsons-ws2_used vsimpsons-ws_avail vsimpsons-ws_used) ;;
moes) WORKSPACES=(barney_avail barney_used carl_avail carl_used lenny_avail lenny_used moes-ws2_avail moes-ws2_used) ;;
flanders) WORKSPACES=(flanders-ws0_avail flanders-ws0_used flanders-ws1_avail flanders-ws1_used flanders-ws2_avail \
flanders-ws2_used maude_avail maude_used ned_avail ned_used rod_avail rod_used todd_avail \

if ! [ -f $OUTPUT_DIR/$HOSTNAME.csv ]; then

echo -n "$separator$v" >> $OUTPUT_DIR/$HOSTNAME.csv # append, concatenated, the separator and the value to the file

它看起来像这样：
simpsons
,bart_avail,bart_used,homer_avail,home_used,lisa_avail,lisa_used,marge_avail,marge_used,releases_avail,releases_used,rt-private_avail,rt-private_used,simpsons-ws0_avail,simpsons-ws0_used,simpsons-ws1_avail,simpsons-ws1_used,simpsons-ws2_avail,simpsons-ws2_used,vsimpsons-ws_avail,vsimpsons-ws_used

你们能帮我减少三个逗号之间的值吗？
在这些3盒（辛普森，教育和体育，和佛兰德斯），以获得正确的果，并使用值的唯一方法是运行在awk这样的：
df -m /export/ws/maude | awk '{if (NR!=1) {print $3, $2}}'
，看起来像这样：
492 163306
否则，如果你像这样运行：
df -m /export/ws/maude | awk '{print $3, $2}'
你得到这样的：
Used 1M-blocks
492 163306
您应该修改您的示例以提供显示行为的* minimal *示例。在你的情况下，这将有点像'awk'我的破碎脚本<< EOF模拟输入到awk EOF'。 – 2014-09-22 04:46:40
@MichaelGrünewald如果你看看我的帖子的底部，我的脚本不会从文件中读取它，它会根据df和awk命令生成输出。我不知道如何做的是在awk循环中添加''{if（NR！= 1）{print $ 3，$ 2}}''。我对awk还不够了解。 – 2014-09-22 04:53:09
'awk'从标准输入中读取数据，因此不用管道输出'df'命令，您可以提供带有五个样本输入行的here-document。此外，你不清楚你在问什么。 “你们能......吗？”之后的段落的目的是什么？“看起来像是第二个没有措辞的。 – 2014-09-22 05:00:48
