How can I search filenames which are starting with xy_* and are created/edited today?

Question

Hello I´m currently trying to search for logfiles which are starting with xy_Number and are created/edited today(not last 24 hrs).

I tried:

find /home/USER/logfilesError/ -maxdepth 1 -type f -daystart -mtime -1 print0 | xargs -0 grep - l xy_*

Output:

find: paths must precede expression: print0

I need to combine:

find -maxdepth 1 -type f -daystart -mtime -1

and

ls | grep -E "xy_"

What I want to achieve is:

Search logfiles from a specific location which today's date and then go a step further and search those files and output the ones which have lines starting with ERROR. (other lines INFO and DEBUG)

---

So the search works fine and I want to go further with checking the files after the search with a grep to find the files containing ERROR

grep -rl "ERROR" /home/USER/logfilesError/

How do I combine those in a script? With If? Can someone help me with this?

Answer 1

Why use grep, find can do the job:

find /home/USER/logfilesError/ -maxdepth 1 -type f -name "xy_*" -daystart -mtime -1

Answer 2

By the sounds of it, you're looking for -name:

find /path -maxdepth 1 -type f -name 'xy_*' -daystart -mtime -1 -exec grep -H ERROR {} +

From man find:

-name pattern

Base of file name (the path with the leading directories removed) matches shell pattern pattern. The metacharacters (‘*’, ‘?’, and ‘[]’) match a ‘.’ at the start of the base name (this is a change in findutils-4.2.2; see section STANDARDS CONFORMANCE below). To ignore a directory and the files under it, use −prune; see an example in the description of −path. Braces are not recognised as being special, despite the fact that some shells including Bash imbue braces with a special meaning in shell patterns. The filename matching is performed with the use of the fnmatch(3) library function. Don’t forget to enclose the pattern in quotes in order to protect it from expansion by the shell.
