Why doesn't find find anything?

阅读更多关于 Why doesn't **find** find anything?

问题 I'm looking for shell scripts files installed on my system, but find doesn't work: $ find /usr -name *.sh But I know there are a ton of scripts out there. For instance: $ ls /usr/local/lib/*.sh /usr/local/lib/tclConfig.sh /usr/local/lib/tkConfig.sh Why doesn't find work? 回答1: Try quoting the wildcard: $ find /usr -name \*.sh or: $ find /usr -name '*.sh' If you happen to have a file that matches *.sh in the current working directory, the wildcard will be expanded before find sees it. If you

问题 I'm looking for a solution (similar to the bash code below) to copy both stdout and stderr to a file in addition to the screen within ksh on Solaris. The following code works great in the bash shell: #!/usr/bin/bash # Clear the logfile >logfile.txt # Redirect all script output to a logfile as well as their normal locations exec > >(tee -a logfile.txt) exec 2> >(tee -a logfile.txt >&2) date ls -l /non-existent/path For some reason this is throwing a syntax error on Solaris. I assume it's

in general we use cd .. for going to the parent directory cd ../../ to go to the parents parent directory. and cd ../../../../../ for 5th parent directory. is there any simplified way of doing this? shell i am using is ksh.

How to read just a single character in shell script

阅读更多关于 How to read just a single character in shell script

I want similar option like getche() in C. How can I read just a single character input from command line? Using read command can we do it? In ksh you can basically do: stty raw REPLY=$(dd bs=1 count=1 2> /dev/null) stty -raw SiegeX In bash, read can do it: read -n1 ans fess . read -n1 works for bash The stty raw mode prevents ctrl-c from working and can get you stuck in an input loop with no way out. Also the man page says stty -raw is not guaranteed to return your terminal to the same state. So, building on dtmilano's answer using stty -icanon -echo avoids those issues. #/bin/ksh ## /bin/{ksh

connect to sqlplus only once without writing to a file in a loop

阅读更多关于 connect to sqlplus only once without writing to a file in a loop

I have a requirement for which I need to write a ksh script that reads command line parameters into arrays and creates DML statements to insert records into an oracle database. I've created a script as below to achieve this. However, the user invoking the script doesn't have permission to write into the directory where the script has to run. So, is there a way we can fire multiple inserts on the database without connecting to sqlplus multiple times within the loop and at the same time, NOT create temp sql file as below? Any ideas are highly appreciated. Thanks in advance! i=0 while (( i<$src
