Add part of directory name to filename

Shell Programming and Scripting
1

Hello,

I need to add a part of folder name to the files inside it. For instance the file is

HMCBackup_20150430.155027.tgz

and it is under directory

/nim/dr/HMCBackup/cops22

I need to add cops22 to the file name so as it would be

cops22_HMCBackup_20150430.155027.tgz

Any help in doing this would be appreciated

Thanks

Hi,

can you try this ?

A=/nim/dir/HMC/cops22
$ echo ${A##*/}
cops22

Hello hasn318,

So let's say you are in path /nim/dr/HMCBackup/cops22 only, then following may help you in same.

cat script.ksh
PWD=`pwd`
VAL=$1
mv $VAL "${PWD##*/}_$VAL"

You could run script.ksh HMCBackup_20150430.155027.tgz and it will change file HMCBackup_20150430.155027.tgz to cops22_HMCBackup_20150430.155027.tgz , you could pass file name which is present in path and it will rename it as above.

Thanks,

./test: line 3: $: command not found
./test: line 4: cops22: command not found

I get this error

Actually I have five different folders and files in it that needs to be changed.

/nim/dr/HMC/cops21
/nim/dr/HMC/cops22
/nim/dr/HMC/cops23
/nim/dr/HMC/cops24
/nim/dr/HMC/cops25

and the files should be named

cops21_HMCBackup_20161011.123704.tgz
cops22_HMCBackup_201610110.134524.tgz

and so on.

Linux/bash

cp filename `echo "${PWD##*/}_filename"`

cp file `echo "{PWD##*/}_filename"`
cp: file: No such file or directory

cp HMCBackup_20161011.123704.tgz `echo "{PWD##*/}_filename"`
cp: {PWD##*/}_filename: No such file or directory

Hello hasn318,

Let's say you have saved all paths into a file named path_names .

cat path_names
/nim/dr/HMC/cops21
/nim/dr/HMC/cops22
/nim/dr/HMC/cops23
/nim/dr/HMC/cops24
/nim/dr/HMC/cops25

Could you please try following code and let me know how it goes then.

while read line
do
	cd "$line"
	for file in *.tgz
	do 
		mv "$file" "${line##*/}_$file"
	done
done < "path_name"

Thanks,
R. Singh

The code you posted is adding all the names of folder

cops21_cops22_cops23_cops24_cops_25_HMCBackup_20161011.123704.tgz

---------- Post updated at 03:32 PM ---------- Previous update was at 03:12 PM ----------

basename `dirname "/nim/dr/HMC/cops21/HMCBackup_20161011.123704.tgz"`

is giving me cops21

Now, I need to append that cops21 to the filename

Can you try this script and let me know how it goes ?

$ tree
.
 cops21
    HMCBackup_20161011.123704.tgz
 cops25
    HMCBackup_20161012.12346.tgz
 try.sh

cat try.sh
#!/bin/bash

find . -name "*tgz" |
while read line
do
echo $line
getext=${line##*.}
getdir=${line%/*}
getdir=${getdir#./*}
justfile=${line#./*/}
justfile=${justfile%.*}
mv $line ./${getdir}/${getdir}_${justfile}.${getext}
done

$ ./try.sh 
./cops25/HMCBackup_20161012.12346.tgz
./cops21/HMCBackup_20161011.123704.tgz

After running the script, i get the output as you said.( renamed files )

$ tree
.
 cops21
    cops21_HMCBackup_20161011.123704.tgz
 cops25
    cops25_HMCBackup_20161012.12346.tgz
 try.sh

That works!!

One thing I noticed is that every time I run the try.sh script, it keeps adding the cops21 to the file name

cops21_HMCBackup_20161011.123704.tgz

becomes

cops21_cops21_HMCBackup_20161011.123704.tgz

that should not be the case, it should only change files which are HMC*.tgz and not cops21_HMC*.tgz

thanks

Try changing

find . -name "*tgz"

to

find . -name "HMC*tgz"
