编辑大量文本文件

OSX有unix命令吗 sed

您可能会说(假设要删除的文本在每个文件中都是相同的):

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' file_pattern
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' file_pattern

例如,假设一堆.txt文件需要在主目录下的这5个目录中进行这些编辑。你可以做:

sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_1/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_2/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_3/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_4/*.txt
sed -i 's/STARTTYPE:RGIN\nMODEXP:NO\n//' /home/Run_Loop/directory_5/*.txt
sed -i 's/REFACTORSCALE:2.0\nENDTYPE:FACTORED\n//' /home/Run_Loop/directory_5/*.txt
