我的脚本的第一部分在一个 debian wheezy 盒子上工作：
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/$HOSTNAME.csv"
else
:
fi
并在每次 cron 在凌晨 3:00 -8GMT 关闭时产生这样的每日输出：
sideshow
,bob_avail,bob_used,mel_avail,mel_used,sideshow-ws2_avail,sideshow-ws2_used
09-20-14,470400,1032124,661826,1032124,43443,1032108
09-20-15,470400,1032124,661826,1032124,43443,1032108
09-20-16,470400,1032124,661826,1032124,43443,1032108
但是由于某种原因，当我尝试在其他 3 个 debian 挤压盒上运行它时，我在值之间得到三个逗号：
case "$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 \

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 \

看起来像这样：
simpsons

你们能帮我将值之间的 3 个逗号减少到 1 个吗？
在这 3 个盒子（simpsons、moes 和 flanders）上，获得正确使用率和使用值的唯一方法是像这样运行 awk：
df -m /export/ws/maude | awk '{if (NR!=1) {print $3, $2}}'
看起来像这样：
492 163306
否则，如果您像这样运行它：
df -m /export/ws/maude | awk '{print $3, $2}'
你得到这个：
