What would be your suggestions for a good bash/ksh script template to use as a standard for all newly created scripts? I usually start (after the #! line) with a commented-out header with a filename, synopsis, usage, return values, author(s), changelog and would fit into 80-char lines. All documentation lines I start with double-hash symbols ## so I can grep for them easily and local var names are prepended with "__". Any other best practices? Tips? Naming conventions? What about return codes? Comments on version control : we use SVN all right, but another dept in the enterprise has a separate

I am new to unix and need some help here. I have two directories present on two different server. both the directories contains the same files. Now i want to check if all files are in sync in both the directories. If files are not in sync then i want to display only name of those files. I am able to do it when directories are on same server. not able to figure out how to do this when directories are present on two different servers. eg: server1 /abc/home/sample1/ server2 /abc/home/sample2/ here i want only files name to display when it not in sync. Thanks in advance kielni You can use rsync

I have a KornShell (ksh) script that logins into SQL*Plus and executing a script. Within the shell script I would like to capture the status code of the SQL statement that was executed. Currently there is an error with SQL and I am unable to capture it by checking $?. How would I capture the success or error code from the sql statement and pass it to the shell script. Snippet of ksh script: sqlplus $JDBC_FBUID_U/$JDBC_FBPWD_U@$JDBC_FBDB @${FBC_HOME}/FBCS003.sql ${outputfile} if [ $? != 0 ] then msg_txt="The execution of Sql script /tmp/FBCS003.sql failed. Please investigate." echo ${msg_txt}

I seem to be running into an issue that's specific to ksh88 that's changing single quotes to double quotes, but only under certain situations involving heredocs and command substitution. Here's an example: #!/bin/ksh # This example works correctly echo "Example 1:" cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF echo # This example is broken echo "Example 2:" var=$(cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF) echo "${var}" echo # This example works correctly echo "Example 3:" var=`cat <<EOF The 'quick' brown fox "jumped" over the lazy dog. EOF` echo "${var}"

I want to read a file line by line in Unix shell scripting. Line can contain leading and trailing spaces and i want to read those spaces also in the line. I tried with "while read line" but read command is removing space characters from line :( Example if line in file are:- abcd efghijk abcdefg hijk line should be read as:- 1) "abcd efghijk" 2) " abcdefg hijk" What I tried is this (which not worked):- while read line do echo $line done < file.txt I want line including space and tab characters in it. Please suggest a way. sat Try this, IFS='' while read line do echo $line done < file.txt EDIT:

I am attempting to work with an existing library of code but have encountered an issue. In short, I execute a shell script (let's call this one A ) whose first act is to call another script ( B ). Script B is in my current directory (a requirement of the program I'm using). The software's manual makes reference to bash , however comments in A suggest it was developed in ksh . I've been operating in bash so far. Inside A , the line to execute B is simply: . B It uses the "dot space" syntax to call the program. It doesn't do anything unusual like sudo . When I call A without dot space syntax, i
