Find all files with a filename beginning with a specified string

Question

I have a directory with roughly 100000 files in it  and I want to perform some function on all files beginning with a specified string  which may match tens of thousands of files   I have tried  ls mystring    but this returns with the bash error  Too many arguments    My next plan was to use  find   mystring  -type f   but this has the same issue     The code needs to look something like  for FILE in  find   mystring  -type f  do      Some function on the file done

ls   grep   abc      will give you all files beginning  which is what the OP specifically required  with the substringabc  It operates only on the current directory whereas find operates recursively into sub folders   To use find for only files starting with your string try     find   -name  abc

If you want to restrict your search only to files you should consider to use -type f in your search  try to use also -iname for case-insensitive search  Example   find  path -iname  yourstring   -type f     You could also perform some operations on results without pipe sign or xargs  Example    Search for files and show their size in MB  find  path -iname  yourstring   -type f -exec du -sm
