我正在处理一些文件,因此,结果可以是任何一种方式。
例如:
>cp -R bin/*.ksh ../backup/
>cp bin/file.sh ../backup/bin/
当我执行上述命令时,它会被复制。如果复制成功,系统无响应。如果没有,则在终端本身cp: file.sh: No such file or directory
中打印错误或响应。
现在,我想记录错误消息,或者如果成功,我想将自定义消息记录到文件中。我能怎么做?
确实有任何帮助。

尝试在shell脚本中写这个:
#these three lines are to check if script is already running.
#got this from some site don't remember :(
ME=`basename "$0"`;
LCK="./${ME}.LCK";
exec 8>$LCK;
LOGFILE=~/mycp.log
if flock -n -x 8; then
# 2>&1 will redirect any error or other output to $LOGFILE
cp -R bin/*.ksh ../backup/ >> $LOGFILE 2>&1
# $? is shell variable that contains outcome of last ran command
# cp will return 0 if there was no error
if [$? -eq 0]; then
echo 'copied succesfully' >> $LOGFILE
