用換行符和“

Question

我有一堆看起來像這樣的文本文件：

His doctor attributed this to an allergy .

That hardly convinced him , as he had no history of allergies of any kind .
" Yet , that was to be the least of his problems .
I may have to take steroids for the rest of my life .
"
A topical steroid spray was later added to his repertoire of drugs and 
" he knew it was merely masking the underlying condition .
"

我想改變它使得. " . "放在一行中。所需的輸出應如下所示：

His doctor attributed this to an allergy .

That hardly convinced him , as he had no history of allergies of any kind .
" Yet , that was to be the least of his problems .
I may have to take steroids for the rest of my life . "
A topical steroid spray was later added to his repertoire of drugs and 
" he knew it was merely masking the underlying condition . "

我已經嘗試過了，但是沒有用：

sed -i 's/.\n"\n/. "\n/g'

有人可以幫助我解決正確的sed命令，以將"向上移動"嗎？

Answer 1

這是我想出的：

sed -n '1{h;d};/^"$/{g;s/$/ "/p;n;h;d};x;p;${g;p}' input.txt

輸出

Answer 2

perl -00 -lpe 's/\n"$/"/mg'

產生所需的輸出。

Answer 3

sed略有不同：

sed -n '1{h};1!{/"$/!H};/"$/{H;g;s/\.[ \n]*"$/\. "/;p;n;x}' input.txt

• 1 { h } —將第一行放入保持緩沖區
• 1! { /"$/ !H } 1! { /"$/ !H } -為線的其余部分，積聚成保持緩沖區，如果沒有寂寞"

• /"$/ { H; g; s/\\.[ \\n]*"$/\\. "/; p; n; x } /"$/ { H; g; s/\\.[ \\n]*"$/\\. "/; p; n; x } -否則：

  1. H添加到保持緩沖區
  2. g —將保持緩沖區移至模式空間
  3. s/\\.[ \\n]*"$/\\. "/ —進行替換
  4. p打印出來
  5. n —閱讀下一行
  6. x並將其保存在保持緩沖區中

Answer 4

這可能對您有用：

sed ':a;$!N;s/\.\n"/."/;P;D' /tmp/a
