Create a soft link for all the files under the folder, the link file can be specified to save to a different directory

When FileList is assigned, you can specify the source path,

In the following "Ln-s $file arm-linux-" $LASTWD "", you can specify the directory of the linked file, such as the source path is the current path, the target path is the current path

#/bin/bash


filelist= ' ls./'


For file in $filelist
Do
firstwd= $file | Cut-d "-"-f1


# if ["$firstwd" = = "Arm"]
# Then
Lastwd= ' echo ' $file | Sed ' s/.*-\ ([^-]*\) $/\1/'
Echo $LASTWD
Ln-s $file arm-linux-"$LASTWD"
# fi
