File Concatenation in a format
I have some files named as:

error_abc.txt

error_def.txt

error_ghi.txt

I want to concatenate all these into a single file say error_all.txt. The error_all.txt should be displayed like:

Code:
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
error_abc:

Errors of abc
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
error_def:

Errors of DEF
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

error_ghi

Errors of GHI:

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""''''''


Thanks Smilie

Try:
Code:
grep "" error_???.txt

I mean the files which are concatenated into a single file should have their description and then the content separated by some symbol.

grep "" error_???.txt this is not working!!

@Scrutinizer:

Code:
grep "" error_???.txt

How to do this in multiple files?

If mean:
Code:
grep "" file1 file2 file3 ... filen > allerrors_file

or
Code:
grep "" file* > allerrors_file

It is not exactly what you are looking for, but it may be close enough..

It appends file names to the lines.

Yes it prepends file names so that you know where the error messages originate from...

head -n -0 file.txt file2.txt file3.txt > all.txt

this does the trick adds the header as the file name but no symbols.
