Shell bash脚本自动搜索代码中的字符串，包括子文件夹
我一直在使用tail、head和grep的组合来打印与我相关的代码。它帮助我找到函数并直接切入要点。我一天大约做30到40次，所以我想我应该在这方面寻求一些帮助，因为我不擅长sh脚本Shell bash脚本自动搜索代码中的字符串，包括子文件夹,shell,grep,head,tail,cat,Shell,Grep,Head,Tail,Cat,我一直在使用tail、head和grep的组合来打印与我相关的代码。它帮助我找到函数并直接切入要点。我一天大约做30到40次，所以我想我应该在这方面寻求一些帮助，因为我不擅长sh脚本 我最终喜欢的命令格式类似于giveme“searchstring”-nn您可以尝试以下脚本： #!/bin/bash shopt -s extglob SEARCHDIR_DEFAULT="./" read -ep "Enter search directory [$SEARCHDIR_DEFAULT]: "

#用法：giveme searchstring[numlines]

/'"$1"'/ {
printf（“=%s==\n”，文件名）；
对于（i=0；请看我的答案。另外，你真的想在文本文件中显示没有匹配模式的行吗？tail-n+line./filename | head-numberoflinestodisplay
@konsolebox我没有匹配模式，我只是在grep-n找到字符串的行后显示x行。因为我不知道字符串的长度函数是，我说，显示我说30行的文件后$TAILLINES@konsolebox每天仍在使用此脚本！感谢您对脚本的帮助！！很高兴知道！欢迎：）我想你错过了尾部-n**+**##的作用，当我添加一个+符号时，它从文件的顶部而不是结尾开始，因此它实际上从grep返回的行开始。我在你的代码SEARCHDIR_DEFAULT=“./”和tail-n+“$TAILLINES”“$file”| head-n“$NUMLINES”中更改了以下内容，但是我需要一个搜索函数来获取grep-n输出中第一个实例：之前的数字，这些数字将成为变量“$TAILLINES”对于那个文件。@Faruq我知道我做了更新。如果对你有效，请点击左边的复选标记接受答案。如果缺少任何东西，请发回。@Faruq数字很多。如何选择用于尾线的数字？还是我们要计算输出？她很漂亮。谢谢，效果很好。我想知道当它为我节省了大量的工作时间时，我就去报道，结果我玩得太多了。她让我的工作更有趣。谢谢你，不用客气。这个脚本做了你所期望的吗？如果没有，请告诉我遗漏了什么。这正是我所期望的，尽管坦率地说，konsolebox的布局只是呈现了一种形式让浏览不同的文件更有趣。你很有钱。
