search a string in all the .log files in a directory using bash script-CodePudding

search a string in all the .log files in a directory and move the name of the file which contains the specified string excluding extension .log to a new .txt file

I have tried this but this is wrong

if grep --include=\*.log -rnw '/path/' -e "scp error"
   then 
     do FILENAME=${f%%.*};  
     echo ${FILENAME} > redrop_files.txt;  
   done;

Please help

CodePudding user response：

You have one main problem: you don't store the results of grep anywhere so variable f is undefined.

It is not clear why you use -n with grep if you only want the filename; -l seems to make more sense.

So:

grep --include=\*.log -rlw '/path/' -e "scp error" |\
while read -r f; do
    echo "${f%%.*}"  
done > redrop_files.txt

Try the following,

path=.
while read file; do
  echo ${file%%:*} >> redrop_files.txt
done < <(grep --include=\*.log -rnw $path -e "scp error")
