find -exec with multiple commands

Question

I am trying to use find -exec with multiple commands without any success   Does anybody know if commands such as the following are possible   find   txt -exec echo    tail -1         ls             Basically  I am trying to print the last line of each txt file in the current directory and print at the end of the line  a comma followed by the filename

I usually embed the find in a small for loop one liner  where the find is executed in a subcommand with      Your command would look like this then  for f in   find   txt   do echo  quot   tail -1  f     ls  f  quot   done  The good thing is that instead of    you just use  f and instead of the -exec     you write all your commands between do and   done  Not sure what you actually want to do  but maybe something like this  for f in   find   txt   do echo  f  tail -1  f  ls -l  f  echo  done

One of the following   find   txt -exec awk  END  print  0     FILENAME          find   txt -exec sh -c  echo    tail -n 1   1    1            find   txt -exec sh -c  echo    sed -n    p    1    1

I don t know if you can do this with find  but an alternate solution would be to create a shell script and to run this with find   lastline sh   echo   tail -1  1   1   Make the script executable  chmod  x lastline sh   Use find   find   -name    txt  -exec   lastline sh

1st answer of Denis is the answer to resolve the trouble  But in fact it is no more a find with several commands in only one exec like the title suggest  To answer the one exec with several commands thing we will have to look for something else to resolv  Here is a example   Keep last 10000 lines of  log files which has been modified in the last 7 days using 1 exec command using severals    references  1  see what the command will do on which files   find   -name    log  -a -type f -a -mtime -7 -exec sh -c  echo tail -10000      gt  fictmp  echo cat fictmp   gt            2  Do it   note no more      but only     this is wanted   find   -name    log  -a -type f -a -mtime -7 -exec sh -c  tail -10000     gt  fictmp  cat fictmp  gt       rm fictmp

find accepts multiple -exec portions to the command  For example   find   -name    txt  -exec echo       -exec grep banana         Note that in this case the second command will only run if the first one returns successfully  as mentioned by  Caleb  If you want both commands to run regardless of their success or failure  you could use this construct   find   -name    txt     -exec echo       -o -exec true       -exec grep banana

Another way is like this   multiple cmd          tail -n1  1       ls  1      export -f multiple cmd   find   txt -exec bash -c  multiple cmd   0           in one line  multiple cmd     tail -1  1  ls  1    export -f multiple cmd  find   txt -exec bash -c  multiple cmd   0             multiple cmd    - is a function  export -f multiple cmd  - will export it so any other subshell can see it  find   txt -exec bash -c  multiple cmd   0          - find that will execute the function on your example   In this way multiple cmd can be as long and as complex  as you need   Hope this helps

A find xargs answer   The example below finds all  html files and creates a copy with the  BAK extension appended  e g  1 html   1 html BAK    Single command with multiple placeholders  find   -iname    html  -print0   xargs -0 -I    cp --          BAK    Multiple commands with multiple placeholders  find   -iname    html  -print0   xargs -0 -I    echo  cp --       BAK   echo     gt  gt   tmp log txt    sh    if you need to do anything bash-specific then pipe to bash instead of sh   This command will also work with files that start with a hyphen or contain spaces such as -my file html thanks to parameter quoting and the -- after cp which signals to cp the end of parameters and the beginning of the actual file names       -print0 pipes the results with null-byte terminators         for xargs the -I    parameter defines    as the placeholder  you can use whichever placeholder you like  -0 indicates that input items are null-separated

Extending  Tinker s answer   In my case  I needed to make a command   command   command inside the -exec to print both the filename and the found text in files containing a certain text   I was able to do it with   find   -name config -type f    -exec  grep  bitbucket        -a -exec echo              the result is       url   git bitbucket org a a git   a  git config     url   git bitbucket org b b git   b  git config     url   git bitbucket org c c git   c  git config
