First, some disclosure: I am not a Linux admin, and my Linux admin is not a programmer. That said, we have a cronjob that runs a mysqlimport command to import a text file that's generated daily. I have no control or involvement in how this file is created. Through trial and error, we discovered that the text file is generated on a Wi...
I have a java application consisting of a Thread that monitors a table in the database that contains shell scripts to be executed. I look up the database, every few seconds. for a script, execute it (via the Process class), and wait for another script in the table. My problem is: At times, some command in the script fails. The thread c...
I am attempting to "grep" out bind for a specific user from an LDAP log file. The lines I need will be spread across multiple lines in the log. Here is example input: [2009/04/28 17:04:42.414] DoBind on connection 0x7c8affc0 [2009/04/28 17:04:42.414] Bind name:cn=admin,ou=appids,o=admineq, version:3, authentication:simple [2009/04/28 17...
Hi All, I know this question has kind-a started "religious" wars in past and there might not be one correct answer. But after working with ksh and csh for last 3-4 years and going through the pain of porting from one to another or applying a common piece of logic to multiple versions (read as legacy code), if I am writing a new script, ...

Need to search a directories with lots of sub-directories for a string inside files: I'm using: grep -c -r "string here" * How can I total count of finds? How can I output to file only those files with at least one instance? ...
For some reason I need my script to be able to accept arguments with space characters. If for example I have a script as follows, for SOME_VAR in $@ do echo "$SOME_VAR" cd "$SOME_VAR" done; if I pass arguments to the script (assuming it is called foo.sh) sh foo.sh "Hello world" I am expecting the script to print Hello world...

How do I find out which executables or processes are using my shared library objects in a Unix environment, specifically the AIX environment. Is there any command for it? ...
Hi all, I have written an if statement of the form: if [ -n "${VAR:-x}" ]; then #do something export VAR=#something fi My shell script calls this statement twice and surprisingly passes the condition twice. [hint (perhaps...): This exact code is repeated in a function in an included file. The if statement is first evaluated pr...
I've been using the following command to grep for a string in all the python source files in and below my current directory: find . -name '*.py' -exec grep -nHr <string> {} \; I'd like to simplify things so that I can just type something like findpy <string> And get the exact same result. Aliases don't seem sufficient since they on...

Example: file1 ------- key1,value1 key2,value2 key3,value3 key5,value5 key7,value7 file2 ------- key1,value1 key3,value3 key4,value4 key5,value5 key6,value6 With this diff-like utilities it will output 3 types of records: Records that only exists...
Given a list of files in files.txt, I can get a list of their sizes like this: cat files.txt | xargs ls -l | cut -c 23-30 which produces something like this: 151552 319488 1536000 225280 How can I get the total of all those numbers? ...
How do I pass the command line arguments to an alias. Here is a sample: alias mkcd='mkdir $1; cd $1;' But in this case the $xx is getting translated at the alias creatin time and not at the runtime. I have, however, created a workaround using a shell function (after googling a little) like below: function mkcd(){ mkdir $1; cd...

Is there any way to debug a bash script? E.g something that prints a sort of execution log like "calling line 1", "calling line 2" etc. ...
At a previous workplace we used to have a highly-refined bash function called run-only-once that we could write into any long-running shell script, and then call it at the start of the script, which would check to see whether the script was already running as another process, and if so exit with a notification to STDOUT. Does anyone hav...
My problem is that I have a bunch of file names without the version appended (version keeps changing everytime). The file names are in a file in a particular sequence and I need to get the latest version from a folder and then sequentially install the same. The logic would be: scan a file with contents read a line from the file using t...
