Hi,
Can someone tell me if it's possible to tell the shell this:
rename foo.bar so that four character are deleted from the end of the file name
Thus the name becomes foo without the .bar extention.
Thanks in advance,
ZiM |

Perhaps not exactly what you wanted, but:
| Code: |
for n in *; do mv $n `echo $n | cut -d'.' -f1`; done
|
Looks at all files in the current directory and cuts away all parts of the file name after the first dot. Messes up if a file name contains spaces or premature dots. All in all just an ugly quickie.
If you like, you can change '*' to '*.mpg' or some other matching criteria. |

Many ways to do this. One way:
| Code: |
for x in *.???; do mv "$x" "${x%.???}"; done
|
The expression in the loop strips out the trailing 4 characters including the ".". |

Felt like twiddling...
A script:
| Code: |
#!/bin/bash
ls -A1 | grep '.\+\..*' | sort | while read OLDFILE
do
NEWFILE=`echo ${OLDFILE} | sed 's/\.[^\.]*$//g'`
mv -f "${OLDFILE}" "${NEWFILE}"
done |
The result:
| Code: | mlang@bigbox test $ ls -a
. .. .test4.test .test5 test1.test test2.test.test test3.t test6.tst
mlang@bigbox test $ rm-ext
mlang@bigbox test $ ls -a
. .. .test4 .test5 test1 test2.test test3 test6 |
This is probably 100x more complicated than it needs to be...I'm a regexp n00b.  |
