cd $DEST
echo "Copy h files..."
for f in $LIST
do
if [ $f -ot $SOURCE/$f ]; then
    echo "update $f"
    cp -far $SOURCE/$f $f
fi
done
echo "Copy c files..."
cd $SOURCE
LIST=`find . -name \*.c*`
cd $DEST
for f in $LIST
do
if [ $f -ot $SOURCE/$f ]; then
    echo "update $f"
    cp -fa $SOURCE/$f $f
fi

• find file name and line number which contains the specified keyword

#!/bin/sh
find . -name \*.h -type f -exec grep $1 -nH {} \;
find . -name \*.hpp -type f -exec grep $1 -nH {} \;
echo "search c files............................."
find . -name \*.c -type f -exec grep $1 -nH {} \;
find . -name \*.cpp -type f -exec grep $1 -nH {} \;

• open the file and start from the specified line number. The target is as this form:

 <filename>:<line_number>

#!/bin/bash
FILE=`echo $1 | cut -d : -f 1`
LINE=`echo $1 | cut -d : -f 2`
 
ARG=""
 
REG='^[0-9]+$'
if [[ "$LINE" =~ $REG ]]; then
ARG="+$LINE"
else
ARG=""

if [ -f "$FILE"  ]; then
vi $FILE $ARG
