AIX Shell function to tail a log file for a specific string or for a specific time
You can try tail -f -n0 "$yourfile" | grep -ql "yourstring" on my Linux, this works (almost) as expected. tail -f -n0 produces all lines that are added to the file, grep -ql quietly looks for a single match of "yourstring" in its input and exits afterwards....

Install a fileset on AIX
The reason why you are getting the error saying that you need the base level fileset, is because you are trying to install an update fileset. The .40 in the fileset version (bos.adt.syscalls.5.3.0.40) indicates that is an update, for you to be able to install that version of the fileset,...

Can't get JRuby to work on AIX machine
OK, so the server admin and I spent two days trying to figure these things out and I can finally summarize the solution we ended up with to get JRuby working on AIX_64. 1 . First and most important of all, I had to install JRuby 1.7.9 since the 1.7.16...
g++ compilation error on AIX unix server
The problem is that GCC's standard library defines std::ios::openmode as an enumeration type with overloaded operators, and in C++03 those operators are not allowed to appear in a constant expression (such as the initializer for an enumerator). It works with the Solaris compiler because (I assume) openmode is just an...
How to do file transfer inside ssh command line?
if you're just copying a file up and then executing a script, and it can't happen as two separate commands you can do: gzip -c srcfile | ssh [email protected] 'gunzip -c >destfile; script.sh' This gzips srcfile, sends it through ssh to the remote end, gunzips it on that side, then...
No swap space detected while installing WLS 12c on AIX 7.1 (Installation Crashes)

I've never installed on AIX but you can try two things. First, run the installer with the -ignoreSysPrereqs option to skip over any memory checks. Second, run the installer "silently" to get more information out. Use the -silent option on the command line when you start the installer. You can...

Echo in AIX Shell behaves weird or any reason behind it
This is because * gets expanded as all files in your current directory. You can avoid it with two ways: As you said, by quoting, which makes shell interpret it as a string and not a parameter: while read line do name=$line echo "$name" <---- echo within quotes done <...

Count number of special character combination of delimiters

Using \\ instead of \ works for me. Not sure why exactly. Probably related to how escape characters are interpreted in bash, awk and awk's regex engine but I'm unable to give a good explanation. $ cat test name | ^surname| ^age | ^city | ^country john | ^doe |...
Why am I experiencing unexpected behavior with Linux signal handling?
linux,windows,unix,signals,aix
You must use sigsetjmp/siglongjmp to ensure the correct behavior when mixing signals and jumps. If you change your code it will correctly work under Linux. You also used the old signal API which not recommended. I encourage you to use the much more reliable sigaction interface. The first benefits will...

Make AIX load all shared symbols at run time?
I found the culprit. I ran 'dump -Tv' on lib1.so and found that the function I expected to be exported was not there (although it did show up in nm, oddly enough). The library was linked with -bexpall so all symbols should be there. I dug deeper into the ld...

getopt is not working on AIX as it does in Linux
The basic issue is that getopt on AIX is not the getopt from linux. The one under linux supports long options, while the one on AIX doesn't. This is the same situation on Mac OSX. It can be solved by not using long options as part of the available options...

Unable to copy using cp command in AIX
Try to copy one of this files individually, to find out if the problem is file-specific. If so, check if the file-path containts something problematic, like a symlink to a not-readable directory.

Is there a moment where a file “doesn't exist” during a rename?
The actual guarantee in POSIX is that if you rename a to b and b already exists, there will be no point in time during the rename when b does not exist. It will refer either to the previously existing b or the new b formerly called a. If b...
Ksh nested substitution
shell,unix,ksh,aix,substitution
ksh has the typeset -n command for this (see here), which I think would be the preferred solution: typeset -n tmp="PROFILE_SCSADP01" result=${tmp[${PROFILE_ACTIVE}]} You could also useeval (be careful) for this: tmp="PROFILE_SCSADP01" result=$(eval echo \${$tmp[${PROFILE_ACTIVE}]}) eval parses the command once before it is run, so after the eval completes, the resulting...
Wrong output of “ if [ -z $var ] ” in aix ksh

Search only directories with permission -find (Bash 4.2)
Just use your find /home/ -name 'core.20*' -mtime +7 -print 2>/dev/null When you want to skip dir's without permission, your script must somehow ask Unix for permission. This is exactly what find is doing: when the toplevel is closed, no time is spent on the tree beneath. The only cost...
sed does not recognize -r flag on AIX
Unless you have a compelling reason to use sed, you could use alternate tools: awk -v OFS=';' '{print NR,$0}' filename would produce the desired output. You could also use perl: perl -ne 'print "$.;$_"' filename It appears that your sed expression would skip lines beginning with a #. As such,...
