List file names based on a filename pattern and file content

Question

How can I use Grep command to search file name based on a wild card  LMN2011    listing all files with this as beginning   I want to add another check on those file content     If file content has some thing like   LMN20113456   Can I use GREP for this   Grep -ls  LMN2011      LMN20113456    What is the proper way to search the file names and its contents using shell commands

Assume LMN2011  files are inside  home me but skipping anything in  home me temp or below   find  home me -name  LMN2011   -not -path   home me temp    -print   xargs grep  LMN20113456

It can be done without find as well by using grep s  --include  option   grep man page says   --include GLOB Search only files whose base name matches GLOB  using wildcard matching as described under --exclude     So to do a recursive search for a string in a file matching a specific pattern  it will look something like this   grep -r --include  lt pattern gt   lt string gt   lt directory gt    For example  to recursively search for string  mytarget  in all Makefiles   grep -r --include  Makefile   mytarget       Or to search in all files starting with  Make  in filename   grep -r --include  Make    mytarget

Grep DOES NOT use  wildcards  for search     that s shell globbing  like   jpg  Grep uses  regular expressions  for pattern matching  While in the shell     means  anything   in grep it means  match the previous item zero or more times    More information and examples here  http   www regular-expressions info reference html  To answer of your question - you can find files matching some pattern with grep   find  somedir -type f -print   grep  LMN2011    that will show files whose names contain LMN2011   Then you can search their content  case insensitive    find  somedir -type f -print   grep -i  LMN2011    xargs grep -i  LMN20113456    If the paths can contain spaces  you should use the  zero end  feature   find  somedir -type f -print0   grep -iz  LMN2011    xargs -0 grep -i  LMN20113456

grep LMN20113456 LMN2011    or if you want to search recursively through subdirectories   find   -type f -name  LMN2011   -exec grep LMN20113456
