mv on multiple file with joker

[Leo The Cat]

Hi Guys

Here 400 files like this:

ls *precl*
aa.precl.test
aaprecl.start
precl.bb
rrpreclyy.start
....


I need to rename all this file as this:
aa.prect.test
aaprect.start
prect.bb
rrprectyy.start
...

What is the best way ? Of course the naive command below
mv *prect* *prect*
doesn't work naturally.


Best regards
Den

You can use:

for FILE in $(ls); do NEWFILE=$(echo $FILE| sed 's/precl/prect/g'); mv $FILE $NEWFILE ; done

Ho to use environment variable with sed like this

MYSOURCE=prect
MYDEST=precl
for FILE in $(ls *$MYSOURCE*); do NEWFILE=$(echo $FILE| sed 's/$MYSOURCE/$MYDEST/g'); mv $FILE $NEWFILE ; done

> for FILE in $(ls); [...]

Or, if "$(ls)" causes problems, start with
"find", and do something similar.

bash$ ls -l
total 1
-rw-r----- 1 SMS 40 5 Mar 19 08:41 a b
-rw-r----- 1 SMS 40 5 Mar 19 08:41 c d
bash$ for file in $(ls) ; do echo $file ; done
a
b
c
d
bash$


bash$ find . -type f
./a b
./c d


"$(ls)" could also make the command line too
long.

About Environment variable, this seems do the job:


MYSOURCE=prect
MYDEST=precl
for FILE in $(ls *$MYSOURCE*); do NEWFILE=$(echo $FILE| sed 's/'$MYSOURCE'/'$MYDEST'/g'); mv $FILE $NEWFILE ; done

Any comment ? except the find insteaf of ls command.

Single quotes in your sed command probably won't expand the environment variables. Use double quote instead.

[Leo The Cat]

This works with single quote ....

Because you're quoting only tiny parts of
the command:
's/'
'/'
'/g'

Not much point in that. The hazards are in
the other parts.

and what about simple:

rename precl prect *
