Ubuntu – bash escaping and find command

convert writes to a different image file. To overwrite original image files use mogrify.

Single file:

mogrify -resize 50% Pic.jpg 

All .jpg files:

mogrify -resize 50% *.jpg

Use double quotes twice, escaped and not escaped: -p"\"$MYPASSWORD\""

#!/bin/sh
source pass.cre
/usr/bin/ssh -p 91899 user@remoteHost 'mysqldump -u db_user -p"\"$MYPASSWORD\"" my_database |  gzip -c >  my_database.sql.gz'

Or an other version

/usr/bin/ssh -p 91899 user@remoteHost "mysqldump -u db_user -p\"'io#bc@14@9$#jf7AZlk99'\" my_database | gzip -c > my_database.sql.gz"

Examples

% source pass.cre
% ssh user@host mysqldump -u root -p$MYPASSWORD    
user@host's password: 
zsh:1: bad pattern: -p#8111*@uu(

% source pass.cre
% ssh user@host mysqldump -u root -p"$MYPASSWORD"
