怎么删除po文件中有共同特征的多行

tiglos

po文件中出现了些这样的行
# File: alignment.c, line: 289
# File: anchorsaway.c, line: 851
# File: combinations.c, line: 1209
# File: cvhints.c, line: 284
# File: cvhints.c, line: 491
# File: cvhints.c, line: 678
# File: cvhints.c, line: 776
# File: displayfonts.c, line: 339
# File: displayfonts.c, line: 543
# File: alignment.c, line: 289
# File: anchorsaway.c, line: 851
# File: combinations.c, line: 1209
# File: cvhints.c, line: 284
# File: cvhints.c, line: 491
# File: cvhints.c, line: 678
# File: cvhints.c, line: 776
# File: displayfonts.c, line: 334
# File: displayfonts.c, line: 531
当然是很多了，删除这些行不影响po内容的。

怎么编个脚本批量删除呢？

tiglos

用这个搞定了
sed '/# File:/d' 20070121d_zh_CN.po >> 20070121e_zh_CN.po

不知道楼主所谓的特征是什么? 如果是以'# File'开头作为特征的话,楼上的代码就很简洁
