Rename bash script help

[mambo84]

Hello,

Would someone please help me by edit a rename script?

I would like a script that can rename file names without disturbing its numbers. Example:

Audit_trail_YYYYMMDD.txt
Audit_trail_YYYYMMDD.txt
Audit_trail_YYYYMMDD.txt
Audit_trail_YYYYMMDD.txt
Audit_trail_YYYYMMDD.txt

Will be renamed to:

KVAT_YYYYMMDD.txt
KVAT_YYYYMMDD.txt
KVAT_YYYYMMDD.txt
KVAT_YYYYMMDD.txt
KVAT_YYYYMMDD.txt

Only the name part will be renamed, and the numbers are left undisturbed.

I tried searching for something like that. But all the scripts I found does the opposite, the result as KVATAudit_trail_YYYYMMDD.txt

here is the script that i found.
originalFiles=$(ls Audit_trail*.txt)
for loopFile in $originalFiles
do
mv $loopFile KVAT$loopFile
done

Please help. Thank in advance.

Hello,
certainly there are countless different possibilities.

What I usually use for this is 'sed' and a pipe, like this:

ls Audit_trail* | sed 's/\(.*\)_\([0-9]*\)\.\(.*\)/mv \1_\2.\3 KVAT_\2.\3/'

or for example:

ls Audit_trail* | sed 's/Audit_trail_\(.*\).txt/mv Audit_trail_\1.txt KVAT_\1.txt/'

You can add ' | head ' at the end to see if it works and then add ' | sh ' instead, to make it work.

Color output of 'ls' can sometimes make troubles, then use 'ls --color=none' instead.

Hi,

It not work for me !

When i try to run the script, it show

-bash: sed: command not found

Any solution for it ?

Thanks

Well mambo84, maybe you don't have sed installed.
Then install it - but that is no more a question to a forum! Google first

Enjoy learning your OS and good luck!

Hi,

i dont hv permission to install sed at FTP server,

i've search from google regarding Rename bash script but all getting same result.

Can use another function other than sed?

Please advice

rename Audit_trail_ KVAT_ Audit_trail_*

Tested the above on a few files I created and it worked. It will affect any file beginning with the "Audit_trail_"

You could test it on a few files you move to the /tmp directory.

Maybe the directory sed is in isn't in your PATH variable. Try specifying the path which should be:

/bin/sed

Bash can do without sed or any other additive.

for file in Audit_trail_*.txt; do
  echo mv "$file" "${file#Audit_trail}KVAT"
done

If you like the output, remove "echo" to do the real work.

However, it's really strange that sed is not installed. It must be some problem with paths or whatever as someone says above.

Hi i92guboj, Can move the KVAT to infront?

[mambo84]

Hi All

Problem solve,

for file in Audit_trail_*.txt; do
  echo mv "$file" "KVAT${file#Audit_trail}"
done

By the way, assume that i got different test file,

Audit_trail_YYYYMMDD.txt --> KVATyymmdd.txt
Mer_net_settle_part1_YYYYMMDD.txt -->KVSAyymmdd.txt

How can i do it in 1 shot?

Please advice.
