copying files and give new unique names to each file by using xargs command
Hello there. Can someone help me. I am trying to copy specific files to current directory and give each of the file a new name by using the xargs command. This is what I have so far but I'm stuck:

ls -l |grep "June"| awk '{print $9}|xargs -ti cp {}

first of all, this:
ls -l |grep "June"| awk '{print $9}'
is wrong.
If the files contain any spaces, you'll mess things up.

Are you searching for files containing June in the filename?

Welcome to LQ forums :)

Yes I am. The command ls -l just gives out a long listing output of all the files under the current directory I'm in. The output then is what I'm trying to manipulate. In this case, I wanted all the June files to be copied with new names. I was hoping to achieve this with the xargs command.

I would use something like this to get the full name:


find . -type f -name "*June*"| while read filename; do ...... done
and every time the loop is executed the $filename variable will contain the next filename.

When you say new names, do you mean random names, specific names, names that follow a pattern (file00 , file01), etc. What exectly do you want?

Thanks. The new file name will only contain character
14-19 of the original name and with the new extension of .csv


rospslpar1_1_050616_0005.nmon (current existing name)

050616.csv (new copied file name)

Try a simple bash script. Something like this should work. I haven't tested it.

find . -maxdepth 1 -type f -name "*rospslpar*" |while read filename; do
 new_name="$(expr substr $base_name 14 6).cvs"
 mv "$filename" "$path_name/$new_name"

Thanks again perfect_circle. This really helps. I'll let you know if it works out or not.
