Search files for a string and if found check if a file with paired name exists in the same directory

findgrepls

I have many different files with the same ending .ft1 that may or may not contain one specific word special. For the files that contain this word, I want to check whether another file with a different ending .log exists in that directory.

What I got so far is this:

find . -name "*.ft1" -exec grep -l "special" {} \; -execdir ls *log \;

However, this gives me an error each time the ls is executed:

ls: cannot access *log: No such file or directory

But I know that there are such files in that directory. I also tried escaping the star, so the expression becomes -execdir ls \*log \;, but the error persists.

I also had a look at this similar question, but I cannot currently see how that helps me with my problem.

How do I get this to behave correctly? Bonus points for a solution that only lists .log files with the same name stem as the found .ft1 files.

Your issue is that you need a shell to interpret the *.log glob. So you need -execdir to invoke a shell. The following snippet will also address your "same name stem" requirement

find . -name "*.ft1" -exec grep -l "special" {} \; \
-execdir bash -c 'x=$1; x=${x%.txt}; ls "$x".log' bash {} \;

Bash – Find files with same name but different content

Update: fixed a typo in the script: changed print $NF to print $3; also tidied things up, and added some comments.

Assuming file names do not contain \n, the following prints out a sorted list which breaks (as in: section control breaks) at unique file name, unique md5sum, and shows the corresponding group of file paths.

#!/bin/bash

# Choose which script to use for the final awk step 
out_script=out_all

# Print all duplicated file names, even when md5sum is the same 
out_all='{ if( p1 != $1 ) { print nl $1; print I $2 }
      else if( p2 != $2 ) { print I $2 }
      print I I $3; p1=$1; p2=$2; nl="\n" }
   END { printf nl}'

# Print only duplicated file names which have multiple md5sums.
out_only='{ if( p1 != $1 ) { if( multi ) { print pend }
                             multi=0; pend=$1 "\n" I $2 "\n" }
       else if( p2 != $2 ) { multi++; pend=pend I $2 "\n" } 
       pend=pend I I $3 "\n"; p1=$1; p2=$2 } 
   END { if( multi ) print pend }'

# The main pipeline 
find "${1:-.}" -type f -name '*' |  # awk for duplicate names
awk -F/ '{ if( name[$NF] ) { dname[$NF]++ }
           name[$NF]=name[$NF] $0 "\n" } 
     END { for( d in dname ) { printf name[d] } 
   }' |                             # standard md5sum output 
xargs -d'\n' md5sum |               # " "==text, "*"==binary
sed 's/ [ *]/\x00/' |               # prefix with file name  
awk -F/ '{ print $3 "\x00" $0 }' |  # sort by name. md5sum, path 
sort |                              # awk to print result
awk -F"\x00" -v"I=   " "${!out_script}"

Output showing only file names with multiple md5s

LS Command – Fix ‘No Such File or Directory’ Error

It sounds to me like it is in heavy use by other processes.

Gathering the information you see is not necessarily atomic. It might get a list of filenames, then go and look up the information on the file (either for a long listing or to color the output). If the file is deleted between those two actions, then you'll get output similar to what you describe.
