没有固定宽度格式的awk打印字符串？

Question

有没有办法让awk不打印固定宽度的列？

例如：

"9", "TAYLOR TOWER, JACOB B. " 
"9", "UNIVERSITY HOSPITALS-EAST" 
"AR", "SCHOTTENSTEIN CENTER  " 
"B1", "NEWARK RESIDENCE HALL " 
"B2", "NEWARK RESIDENCE HALL " 
"CC", "OHIO STADIUM    " 
"D1", "TELECOM NETWORK CENTER " 
"DC", "SCHOTTENSTEIN CENTER  " 
"EN", "SCHOTTENSTEIN CENTER  " 
"GR", "UNIVERSITY HOSPITALS-EAST" 
"LL", "RANEY COMMONS, 2ND LT. AL" 
"MZ", "PHYSICS RESEARCH  " 
"MZ", "SCHOTTENSTEIN CENTER  " 
"NS", "STARLING LOVING HALL " 
"P1", "OHIO STADIUM    " 
"P2", "OHIO STADIUM    " 
"P3", "OHIO STADIUM    " 

我想这被打印为：

"9", "TAYLOR TOWER, JACOB B." 
"9", "UNIVERSITY HOSPITALS-EAST" 
"AR", "SCHOTTENSTEIN CENTER" 
"B1", "NEWARK RESIDENCE HALL" 
"B2", "NEWARK RESIDENCE HALL" 
"CC", "OHIO STADIUM" 
"D1", "TELECOM NETWORK CENTER" 
"DC", "SCHOTTENSTEIN CENTER" 
"EN", "SCHOTTENSTEIN CENTER" 
"GR", "UNIVERSITY HOSPITALS-EAST" 
"LL", "RANEY COMMONS, 2ND LT. AL" 
"MZ", "PHYSICS RESEARCH" 
"MZ", "SCHOTTENSTEIN CENTER" 
"NS", "STARLING LOVING HALL" 
"P1", "OHIO STADIUM" 
"P2", "OHIO STADIUM" 
"P3", "OHIO STADIUM" 

注意在本文中，第二字段具有引号内没有空格。这可能吗？

Answer 1

在AWK（GAWK/NAWK）

{sub(/[ ]*\"$/, "\"");print} 

Answer 2

我会用sed，而不是awk的，尽管你可以，如果你必须做gsub在AWK：

sed -e 's/ *"$/"/' 

含义“打开一个或多个空格，然后报价在该行的末尾逼到报价“
