Question

我试图计算特定字符串的出现次数＆＃34; PhD＆＃34;在文件＆＃39; X＆＃39;中，将该计数＃（例如3），并将/ cat打印到另一个文件的开头，3次，此特定字符串

Graduate StudentID 1
Graduate StudentID 2
Graduate StudentID 3

StudentID之后的数字反映了计数。

我对这一点毫无希望的尝试是（$ OUT应该写入文件）并且我不确定如何解决（明显的）结果错误。

find /home/college/Applications/Graduate -name "*.inp" -exec sed 's/[PhD]//g' input | uniq -c print >$OUT {$1} \;

Answer 1

我将如何做到这一点：

    <?xml version='1.0' encoding='utf-8'?>

这假设您的输出文件名是#!/bin/bash # Count number of occurrences # Use -o | wc -l instead of -c to count multiple occurrences in same line count=$(grep -ro 'PhD' --include='*.inp' /home/college/Applications/Graduate | wc -l) # Intermediate file tmp=$(tempfile) # Output file out=outfile.txt { # Print header lines for (( i = 1; i <= count; ++i )); do printf '%s %d\n' 'Graduate StudentID' "$i" done # Print existing contents cat "$out" } > "$tmp" # Rename intermediate file mv "$tmp" "$out"

count字符串并打印到新的outfile
