Linux Shell Script * or ???? is replace automatically - linux

Question

I have some files stored on a server. I have to get all those files using a pattern and exclude the file which contains the current date as the file name.
Files are given below
/var/tomcat/logs/catalina.2022-05-11.log
/var/tomcat/logs/catalina.2022-05-13.log
/var/tomcat/logs/catalina.2022-05-14.log
/var/tomcat/logs/catalina.2022-05-16.log
/var/tomcat/logs/error_1.log
/var/tomcat/logs/error_2.log
/var/tomcat/logs/error_3.log
/var/tomcat/logs/error_4.log
For this, I have stored patterns in a file and I want to read the pattern of that file and find all files with the help of those patterns.
Pattern Input File content is given below, in below I have used '%Y-%m-%d' to identify the date format so that I can exclude the current date file.
/var/tomcat/logs/catalina.*.log;%Y-%m-%d
/var/tomcat/logs/error_*.log
I have developed a shell script which is given below
#!/bin/sh
pattern_filepath=$1
while IFS= read -r line || [ -n "$line" ]; do
pattern_var="$line"
echo pattern: "$pattern_var"
filepath=""
date_format=""
if [[ $pattern_var == *";"* ]];
then
echo "Semicolons ; separator is there"
filepath=($(echo "$pattern_var" | cut -f1 -d ';'))
echo filepath: "$filepath"
date_format=($(echo "$pattern_var" | cut -f2 -d ';'))
else
echo "Semicolons ; separator is not there"
filepath=$pattern_var
fi
echo "date_format: "$date_format
done < "$pattern_filepath"
Command to run the script
sh /var/monitoring/test.sh "/var/monitoring/pattern" > /var/monitoring/test.log
Inside the log file, I can see, that in the file path variable I am getting the value as a date but that should be with an asterisk instead of a date.
Log file 'test.log'
pattern: /var/tomcat/logs/catalina.*.log;%Y-%m-%d
Semicolons ; separator is there
filepath: /var/tomcat/logs/catalina.2022-05-11.log
date_format: %Y-%m-%d
pattern: /var/tomcat/logs/error_*.log
Semicolons ; separator is not there
date_format:
Please help me with this, how can I achieve this?

Simple, straight to the point. Achieves the requirement, without the complexity of patterns, or lists, or ...
#!/bin/bash
sourcedir="/var/tomcat/logs"
if [[ ! -d "$sourcedir" ]]
then
echo "ERROR: source directory $sourcedir does not exist."
exit 1
fi
targetdir="/tmp/somedir"
if [[ ! -d "$targetdir" ]]
then
echo "ERROR: target directory $targetdir does not exist."
exit 1
fi
# Get the catalina logs
cp "$sourcedir"/catalina.*.log "$targetdir"
# Remove the catalina log for today
filetoremove="$targetdir"/catalina.$(date +%Y-%m-%d).log
if [[ -f "$filetoremove" ]]
then
rm -f "$filetoremove"
fi
# Get the error logs
cp "$sourcedir"/error_*.log "$targetdir"
You can add error checking and recovery for the cp and rm commands.
