如何从Unix shell脚本中的字符串中删除字符？

Question

I have several files that are named like this: file - name.txt

How do I remove the " - " using a bash script in UNIX from all the files?

Answer 1

如果我理解正确，请尝试rename ' - ' '' *

Answer 2

Sed it up!

# Iterate each file in the current directory.
for i in *; do
  # Move the file to the new filename, replacing ' - ' with '_'
  mv "$i" `echo $i | sed 's/ - /_/g'`
done

Answer 3

Use parameter expansion to remove the part of the string you want to be rid of. Make sure to use double-quotes to prevent mv from misinterpreting input.

for i in ./*' - '*; do
    mv "$i" "${i// - }"
done
