S3 copy

You cannot copy from remote to remote. You need to first copy locally and then copy to remote, or vice versa.

If you need to copy from local to s3 you need to setup public ACL then or add policy to allow public access to uploaded files.

## You may choose to remove --recursive if is required only for the bucket or folder and not for objects within.
s3cmd setacl --acl-private --recursive s3://mybucket-name
s3cmd setacl --acl-private --recursive s3://mybucket-name/folder-name
s3cmd setacl --acl-private --recursive s3://mybucket-name/folder-name/object-name
s3cmd setacl --acl-public --recursive s3://mybucket-name
s3cmd setacl --acl-public --recursive s3://mybucket-name/folder-name
s3cmd setacl --acl-public --recursive s3://mybucket-name/folder-name/object-name

For example:

s3cmd sync --skip-existing . s3://sonic/rs/ -c ~/.s3cfg-digitalocean
s3cmd info s3://sonic/ -c ~/.s3cfg-digitalocean
s3cmd setpolicy ~/polisa.json s3://sonic/ -c ~/.s3cfg-digitalocean
s3cmd setpolicy ~/polisa.json s3://sonic/ -c ~/.s3cfg-digitalocean
s3cmd sync --skip-existing s3://leaflets/rs/ ./

cat ~/polisa.json
{"Id":"PublicSharePolicy","Version":"2012-10-17","Statement":[{"Action":["s3:*"],"Effect":"Allow","Resource":["arn:aws:s3:::sonic","arn:aws:s3:::sonic/*"],"Principal":"*"}]}

Excel: Search two strings in two columns

You cannot compare it with = sign.

You need to use:

For partial recognition:

=ISNUMBER(SEARCH(B1,A1))

For exact recognition:

=EXACT(C2,F2)

Make sure to trim cell before comparing if you are using EXACT function or otherwise you are going to get bad results.

Excel unmerge and copy data to fill missing

  1. Unmerge all cells in column A and B
  2. Select all rows in column A and B from your first row of data to your last row of data.
  3. Press CTRL+G to open the Go To box
  4. Click Special
  5. Choose Blank Cells
  6. In the formula bar enter = then press the Up arrow. You’ll end up with a formula like =A3. DO NOT PRESS ENTER
  7. Press CTRL+ENTER and this will populate your formula to all selected cells and simulate a “fill down”.
  8. Copy-paste as values as required.

PostgreSQL remote connection

Problem: Cannot connect remotely mysql or postgresql

Solution:

Allow ports 3306 for mysql or 5432 for pgs.

Go to /etc/mysql/mariadb.conf.d/50-server.cnf and change bind-address = 0.0.0.0. Restart mysql pr maria actually.

Go to hestiacp postgresql configuration part. Go and change listen_addresses = ‘*’, remove comment. Restart psg.

Done.

Delete duplicate entries mysql

t1.id < t2.id AND
t1.page = t2.page AND
t1.catalogues_id = t2.catalogues_id;

Adminer without password

Very important sometimes.

Download adminer .php and then change this on line 1152.

login($_e,$F){if($F==””)return to login($_e,$F){if($F==”abc”)return.

Save and you are good to go. Delete after everything has been setup and working ok.

Change character in filename linux bash

I’m figuring this out for some time. It’s not that I can’t read but most of the time when trying out bash stuff you can make more damage then good to your system so you have to be really really easy.

Now, this one here makes the difference. I had a job to change & in many many many files in different directories and subdirectories and after trying many scripts this one came up working just fine and fast.

find . -type f -exec rename 's/string1/string2/g' {} +

If you want to target specific filename extension then you need to add:

find . -type f -name "*.webp" -exec rename 's/&/-/g' {} +
