how to remove files that could be with lower/upper case

Question

how to remove files that could be with lower/upper case

for example, the file_name could be:

• STOCK.Repo or
• Stock.REPO or
• stOCK.repo or
• stock.repo
• ... etc

I would run:

 rm -f $file_name

the goal is to remove file as stock.repo that could be in lower/upper case on remote machine

Answer 1

For Bash-specific solution:

$ shopt -s nocaseglob

and then run the rm command.

Note to unset this option, use shopt -u nocaseglob

For completeness, I would point out an alternative but less elegant solution:

$ rm [sS][tT][oO][cC][kK].[rR][eE][pP][oO]

Answer 2

You can do it using find command

find /path/to/directory -type f -iname stock\.repo -exec rm -f {} \;

But be very careful. It is working recursively from /path/to/directory. You should consider using maxdepth option, and getting more familiar with this command before running it on production system where permanent damage can be made.

Answer 3

With the zsh and ksh93 shells, you can turn case-insensitive matching on a per-glob basis:

• zsh:

  set -o extendedglob # best in ~/.zshrc
  rm -- (#i)$filename
  

• ksh93:

  rm -- ~(i:"$filename")
  

  Note however, that if there's no matching file a literal ~(i:stock.repo) would be passed to rm. And if that file exists, it would be removed (zsh above would fail with an error and not call rm at all in that case).

  You could however set the N flag in addition to the i flag:

  rm -- ~(Ni:"$filename")
  

  Then, in case of no-match, rm would be called, but with an empty argument (probably a bug caused by the quotes as it's meant to pass no argument at all then). You'd then get a rm: cannot remove '': No such file or directory kind of error but at least it wouldn't remove the wrong file.

Answer 4

I have done by using below method. Answer provided above is quite good. Below one is my try

ls -ltr | awk '{print $9}' | sed -n '/^STOCK.Repo$/Ip'  |awk '{print "rm" " " $1}'| sh
