我有一个bibtex文件(从Zotero导出),我想通过删除特定字段来清理它。
例如,从以下条目中删除文件字段:
@inproceedings{sridharan_fast_2008,
title = {Fast {Rates} for {Regularized} {Objectives}.},
urldate = {2014-03-26},
booktitle = {{NIPS}},
author = {Sridharan, Karthik and Shalev-Shwartz, Shai and Srebro, Nathan},
year = {2008},
pages = {1545--1552},
file = {3400-fast-rates-for-regularized-objectives.pdf:/home/johnros/.zotero/zotero/66g0wvis.default/zotero/storage/6ND67P5F/3400-fast-rates-for-regularized-objectives.pdf:application/pdf}
}

您可以很轻松地使用grep
执行此操作:
grep -v "^\s*file =" bibtext.txt
上一条记录的尾随逗号应该不是问题... see here。
或者,如果你真的热衷于awk
:
awk '!/file = /' bibtext.txt

我不熟悉bibtex
格式,如果有一些工具可以更好地编辑这些格式,那么你应该选择这些工具。
如果你想使用awk
来处理它,这里有一个gnu awk one-liner:
awk -v RS=',\n\\s*file\\s*=\\s[^\\n]*' '7' file
基本上,它只是使用RS
变量,删除file=
行以及前一个结束逗号","
,以便保持生成的输出仍然是有效的bibtex格式。 (我希望是这样)。
用你的例子测试:
kent$ cat f
@inproceedings{sridharan_fast_2008,
title = {Fast {Rates} for {Regularized} {Objectives}.},
urldate = {2014-03-26},
booktitle = {{NIPS}},
author = {Sridharan, Karthik and Shalev-Shwartz, Shai and Srebro, Nathan},
year = {2008},
pages = {1545--1552},
file = {3400-fast-rates-for-regularized-objectives.pdf:/home/johnros/.zotero/zotero/66g0wvis.default/zotero/storage/6ND67P5F/3400-fast-rates-for-regularized-objectives.pdf:application/pdf}
}
kent$ awk -v RS=',\n\\s*file\\s*=\\s[^\\n]*' '7' f
@inproceedings{sridharan_fast_2008,
title = {Fast {Rates} for {Regularized} {Objectives}.},
urldate = {2014-03-26},
booktitle = {{NIPS}},
author = {Sridharan, Karthik and Shalev-Shwartz, Shai and Srebro, Nathan},
year = {2008},
pages = {1545--1552}
}

我知道这是一个较老的问题,但对于那些仍然发现这一点的人:Zotero(Zotero Better BibTeX)的扩展允许您在Zotero内部执行此操作。完全披露:我是此扩展的作者。
