Now create a batch file called 'ReNameFile. Then the first file will get clobbered when the second one is renamed. Make batch file called 'RunMe.bat' with the following code: Code: dir /b find 'pdf' /i > temp.log set tempvar for /f 'tokens1-2 delims.' /f A in (temp.log) do ( renamefile.bat A B ) del temp.log. Then they will both be renamed to A Star is Born.mp4 Note that, if you have A Star is Born-dQw4w9WgXcQ.mp4 Is a relatively recent addition to Bash YMMV.) Given the part about needing a space after the colon for negative numbers, you can do this: #!/bin/bashīy first doing echo mv - "$f" "$.mp4",Īnd then taking out the echo when the dry run produces acceptable results. Note that a negative offset must be separated from the colon by at least one space toĪvoid being confused with the :- expansion. The expansion is the characters between offset and that result. To a number less than zero, it is interpreted as an offset in characters from the end of the value of parameter rather than a number of characters, and If offset evaluates to a number less than zero, the value is used as an offset in characters from the end of the value of parameter. length and offset are arithmetic expressions (see ARITHMETIC EVALUATION ). Of the value of parameter starting at the character specified by offset and extending to the end of the value. If length is omitted, expands to the substring Indexed array subscripted by or *, or an associative array name, the results differ as described below. Expands to up to length characters of the value of parameter starting at the character specified by offset. Using a batch file I would really like to be able to remove the first x amount of characters (3 in this case), so it would go from '05.FILE5' to 'FILE5.' On this thread.

If the character is flagged as 'REMOVE' then it should be removed, and nothing be put in it's place, for example a file named JohnSykes.doc would become JohnSykes. So you could use bash parameter expansion to do this: Any character with 'MAKE -' next to it needs to be made a - (hyphen) in place of the character, for example a file named John\Sykes.doc needs to become John-Sykes.doc. Look at the file again, and when you are positive that it's what you want, execute it with sh /tmp/bulk-rename.One way to think of this is you want to remove the last 16 characters including extension, That file now contains a lot of lines like mv -n "foo" "bar" mv -n prevents overwriting an existing file. The sed part adds a mv -n to the start of each of those lines. What that paste command does is it takes one line from /tmp/old.txt and one line from /tmp/new.txt and puts them together on one single line with a blank between them. Then put the files together with the paste command and change each line to a mv command: paste /tmp/old.txt /tmp/new.txt | sed -e 's/^/mv -n /' >/tmp/bulk-rename In any case, have a good hard look at /tmp/new.txt to see if it's really what you want the new names to look like.Ĭheck for duplicate names! ( sort /tmp/new.txt | uniq -r) Make sure there are no duplicates and if there are, edit that line manually to get a unique name. Important: do not change the order in that file, and do not delete or add any line!

Then replace unwanted characters in /tmp/new.txt, either manually with an editor or with sed -i -e (or perl -p -i -e if you prefer that) or tr or tr -d. Type: Batch file rename : Search all Batch file rename examples: Description: How to batch remove the last 6 characters of many filenames Input Sample: filea(1998).dat fileb(2001).dat filec(2002).dat : Output Sample: filea.dat fileb.dat filec. it will give you "foo*bar" or "foo | bar". Ls -Q will add double quotes around each name, i.e. In general, mmv is great at mass-renaming tasks.īut in this particular case, I'd go a completely different route: Generate a shell script with a couple of shell commands, have a close look at it if it's really what I want, and then execute it.
