UNIX :renaming the files present in the directory

Shell Programming and Scripting
1

Hi all,

I am looking for a script which renames all the files from the present directory.

Eg.:
In unix directory contains the below files

linux001.txt
linux002.txt
linux003.txt
......
.......

Now the files should be renamed to

unix001.txt
unix002.txt
unix003.txt

Could anyone please help me on the above requirement.

Thanks in advance...

Regards,
J

its a sample code..try with relevant names/paths. use the mv command instead.

for i in `seq -f 'linux%03.f.txt' 1 100`; do  echo $i; echo $i|awk '{ gsub(/^linux/,"unix",$0);print}'; done

for i in `seq -f 'linux%03.f.txt' 1 100`; do  mv $i  `echo ${i/linux/unix}`; done

for i in linux*.txt
do
cp -p "$i" unix"${i#*x}" && rm "$i"
done

busyboy is on the right track! Try

$ for i in linux*; do echo mv $i ${i/linux/unix}; done
mv linux001.txt unix001.txt
mv linux002.txt unix002.txt
mv linux003.txt unix003.txt

Remove echo if happy with results.

Hello everybody,

I'm still a newbie, but here's my attempt:

$ for i in * ; do mv $i uni${i##linu}; done

# i=linux001.txt
# echo $i
linux001.txt
# echo ${i#*x}
001.txt
# echo unix${i#*x}
unix001.txt

#! /bin/bash
list=(`ls`);
j=0;
len=${#list
[*]};
while [ $j -lt $len ]
do
mv ${list[$j]} $(echo ${list[$j]} | sed 's/linux/unix/g');
j=`expr $j + 1`;
done

Folks, the

echo unix${i#*x}

is most portable (Posix shells).
But in this case please make it better readable:

echo unix${i#linux}

scriptscript has all my sympathy, because obviously is moving from Linux to Unix :smiley:

for i in $(ls linux*.txt)
do
   m=${i/linux/unix}
   mv $i $m
done

First test in some temporary directory before you run it in production environment
