使用Bash腳本編輯文本文件

Question

我有以下格式的文件：

axel localhost> localhost>
mike localhost> STORAGE 298390/512000 (58.279296875%) localhost>
ab localhost> STORAGE 141361/512000 (27.6095703125%) localhost>
fghi localhost> localhost>
abcd localhost> STORAGE 165929/512000 (32.4080078125%) localhost>
lmno localhost> STORAGE 353073/512000 (68.9595703125%) localhost>
nuon localhost> localhost>
spar localhost> STORAGE 203766/512000 (39.798046875%) localhost>
fibo localhost> STORAGE 238204/512000 (46.52421875%) localhost>
nacci localhost> STORAGE 425737/512000 (83.1517578125%) localhost>
seldom localhost> STORAGE 69894/512000 (13.651171875%) localhost>
project localhost> STORAGE 86220/512000 (16.83984375%) localhost>
eccleston localhost> STORAGE 240084/512000 (46.89140625%) localhost>
swan localhost> STORAGE 279522/512000 (54.594140625%) localhost>

這是通過所產生的輸出listquota在cyradm（賽勒斯-IMAPD）。 我有兩個問題;

• 在那些具有localhost> localhost> ，應將第一個單詞寫入另一個文件，並刪除該行。
• 對於其他行，需要刪除第二列，第三列和最后一列。

我將如何實現這一結果？

預期產出

mike 298390/512000 (58.279296875%)
ab 141361/512000 (27.6095703125%)
abcd 165929/512000 (32.4080078125%)
lmno 353073/512000 (68.9595703125%)
spar 203766/512000 (39.798046875%)
fibo 238204/512000 (46.52421875%)
nacci STORAGE 425737/512000 (83.1517578125%)

到目前為止我的循環看起來像：

while read thisline; do
    if [ $2 == "localhost>" AND $3 == "localhost>" ];then
        echo $1 >>/root/names.txt
        sed '1d' filename.txt #but this deletes only the first line
    fi

done

嘗試這個：

awk '/localhost> localhost>/{print $1 >"file2";next}{$2=$3=$NF=""}7' file

這將輸出您想要的文本，並為localhost> localhost> case生成“file2”。

沒試過，我希望沒有錯字。
