A simple shell script

　　I recently learned about shell programming in linux. I tried to write a small script that traverses the subdirectories of the resource directory and copies 10 files in each resource subdirectory to the target target. There is no technical content, just to prevent yourself from forgetting.

#!/bin/sh
SRCROOT=/vsu/data2/datasource/NPM/fiveminute
SRCPATH=NULL

MYROOT=/var/monitor/sample
MYPATH = NULL

CNT=0
MAXCNT=10

`rm -fR $MYROOT` 2>/dev/null

for P in $(ls -l -A $SRCROOT|awk '/^d/ {print $9}'); do
	SRCPATH=$SRCROOT/$P
	MYPATH=$MYROOT/$P
	`echo "mkdir -p $MYPATH"` 2>/dev/null
	`echo "cp $SRCPATH/head.txt $MYPATH/"` 2>/dev/null
	echo "deal with directory $SRCPATH"
	
	CNT=0
	for F in $(find $SRCPATH -name *.txt); do
		`echo "cp $F $MYPATH/"`
		CNT=`expr $CNT + 1`
		if [ $CNT -ge $MAXCNT ]; then
			break
		be
	done
	echo "done"
done
