Tcl has a good free-form date scanner, if you have Tcl installed (try which tclsh). A shell function: tcldate() { d=${1:-now} # the date string f=${2:-%c} # the output format echo “puts [clock format [clock scan {$d}] -format {$f}]” | tclsh } In action on an ancient Solaris 8 box with bash 2.03 and tcl … Read more
You configure the Sonar task to upload unit test and cobertura reports generated by other parts of your build logic. This is in contrast to Maven which has a standard build life-cycle that Sonar is able to leverage. Unit test and code coverage The following logic runs the unit tests with cobertura instrumented classes. An … Read more
grep itself is able to do so. Simply use the flag -f: grep -f <patterns> <file> <patterns> is a file containing one pattern in each line; and <file> is the file in which you want to search things. Note that, to force grep to consider each line a pattern, even if the contents of each … Read more
Edit: The modern (GNU/Linux) solution, as mentioned in comments years ago 😉 . awk ‘{ arr[$1]+=$2 } END { for (key in arr) printf(“%s\t%s\n”, key, arr[key]) }’ file \ | sort -k1,1 The originally posted solution, based on old Unix sort options: awk ‘{ arr[$1]+=$2 } END { for (key in arr) printf(“%s\t%s\n”, key, arr[key]) … Read more
No, it is not ok. All commands in a pipeline execute at the same time, and the shell prepares redirections before executing the commands. So, it is likely that the command will overwrite the file before cat reads it. You need sponge(1) from moreutils.
You are reading the file line-by-line, so only the first line matches your regex. What you’ll want to do — if you truly wish to delete most of the content — is to slurp the file by using the -0 option, e.g. -0777. This is line ending processing, and 777 is just a number used … Read more
First of all, you should consider broadcast obsolete, specially INADDR_BROADCAST (255.255.255.255). Your question highlights exactly one of the reasons that broadcast is unsuitable. It should die along with IPv4 (hopefully). Note that IPv6 doesn’t even have a concept of broadcast (multicast is used, instead). INADDR_BROADCAST is limited to the local link. Nowadays, it’s only visible … Read more
Try this: Save the script as apt-proxy (without the .sh extension) in some directory, like ~/bin. Add ~/bin to your PATH, typing export PATH=$PATH:~/bin If you need it permanently, add that last line in your ~/.bashrc. If you’re using zsh, then add it to ~/.zshrc instead. Then you can just run apt-proxy with your arguments … Read more
Looking at the paths in the error it seems that you are not using eclipse from the ubuntu repositories (that’s fine imo). Check if the jvm is 64 or 32 bit. java -version will tell you. If you find this is a 64-bit jvm then go back to eclipse.org and download a eclipse version for … Read more
