[SOLVED] bash find

NevemTeve · 06-11-2022, 11:07 PM

Maybe another example will help:

Code:

for i in pavel@devel1 pedro@qa admin@product1 admin@product2; do
    echo "=== $i ==="
    ssh "$i" 'find / -type f -name temp.txt' </dev/null
done

done

Code:

user@server:~$ su - s1
ssh server
[s1@ts1/server ~]$ switchuser
switchuser@server ----------->

this is how we connect and from swichuser@server.. there are temp.txt files under /app/tmp/

in the sameway: we have many users say s2, s3, s4...

for ex: to find second temp.txt on s2, but this is manual..

Code:

user@server:~$ su - s2 
ssh server (ssh instance)
[s2@ts1/server ~]$ switchuser 
switchuser@server ----------->

I cannot help but noticing you keep adding bits to your problem instead of describing every details once.
You can use su -c on local or remote side. Or both. E.g.

Code:

su localuser2 -c "ssh -t remoteuser1@host \"su remoteuser2 -c \\\"find /tmp -name temp.txt -type f\\\"\""

Note: I didn't created this manually, it was a script:

Code:

quote() {
    printf '"%s"' "$(sed 's/[\\"]/\\&/g' <<<"$1")"
}

CMD1='find /tmp -name temp.txt -type f'
CMD2='su remoteuser2 -c '$(quote "$CMD1")
CMD3='ssh -t remoteuser1@host '$(quote "$CMD2")
CMD4='su localuser2 -c '$(quote "$CMD3")
set | grep CMD

Thank you so much. I will try

@1s440: Indeed. It would be helpful for everyone, especially yourself, if you could take the time to write up minimal but a complete description of what you are trying to accomplish which includes all relevant constraints and goals. Please remember that those willing to offer help here are volunteering their time to help solve your problem. Help them help you and show respect for their kindness by helping them to understand the problem as clearly and quickly as possible.

You may find it helpful to review the Site FAQ for guidance in asking well formed questions. Especially visit the link from that page, How to Ask Questions the Smart Way for discussion of things to consider when asking others for help.

Good luck!

so i will put it in simple. I would need a find command to look for the temp.text in /app and its subdirectories and read the content
and present collectively.

Code:

find /app -name temp.txt -exec cat {} +

Weird to have a directory called "/app" though.

i have tried something like this but i have a problem in displaying its conents for ex:

Code:

find /app -name '*versions.txt' -print -exec cat {} +  > files.list

it displays

Code:

/app/tmp/folder/temp.txt
/app/oracle/scp/temp.txt

and then the output of the temp.txt later

it would be good if we get output

/app/tmp/folder/temp.txt

output

/app/oracle/scp/temp.txt

output

Why are you adding the "-print" option?

That's not what you asked in #21.

tp present the output clearly..

Nothing is clear so far as you keep moving the target.
Here is something you might think of:

Code:

find /path -name whatnot -type -print |
while read Name; do echo "=== $Name ==="; cat -- "$Name"; done

I am not sure how can i explain in betterway:

Code:

find /app -name '*temp.txt' -print -exec cat {} +  > files.list

you get output

Code:

/app/tmp/folder/temp.txt
/app/oracle/scp/temp.txt

--- ouput of temp.txt file

--- ouput of temp.txt file

is there a way that we get output of each txt files for ex: to be readable easily

Code:

/app/tmp/folder/temp.txt

--- ouput of txt file
/app/oracle/scp/temp.txt

--- ouput of txt file

Here is an idea you might find familiar from earlier:

Code:

find /app -name '*temp.txt' -type f |\
while read Name; do echo "=== $Name ==="; cat -- "$Name"; done

boughtonp · 06-13-2022, 07:51 AM

When multiple files are passed to tail, it precedes their outputs with the filename (between "==> " and " <==" ).

If the files are longer than 10 lines long, the -n option accepts +1 to mean "start from line one", and thus can be used to output everything.

In other words, replace "cat" with "tail -n+1" and remove the print.

and you will get the next request.....
What I can suggest to the OP:

Code:

find /app -name '*temp.txt' -type f -exec <my_shell_script> {} \;
# and my shell script:
echo "$1"
cat "$1"
# or modify if you wish something else
