these are some aliases you can use in bashrc to shorten the amount of typing needed to use apt-get, also can be used as reference if you can't remember alot of commands or command parameter variations,etc... Please comment with more apt-get aliases if I missed any, thx Show Sample Output

-r ? указывает на то, что нужно рекурсивно переходить по ссылкам на сайте, чтобы скачивать страницы. -k ? используется для того, чтобы wget преобразовал все ссылки в скаченных файлах таким образом, чтобы по ним можно было переходить на локальном компьютере (в автономном режиме). -p ? указывает на то, что нужно загрузить все файлы, которые требуются для отображения страниц (изображения, css и т.д.). -l ? определяет максимальную глубину вложенности страниц, которые wget должен скачать (по умолчанию значение равно 5, в примере мы установили 7). В большинстве случаев сайты имеют страницы с большой степенью вложенности и wget может просто ?закопаться?, скачивая новые страницы. Чтобы этого не произошло можно использовать параметр -l. -E ? добавлять к загруженным файлам расширение .html. -nc ? при использовании данного параметра существующие файлы не будут перезаписаны. Это удобно, когда нужно продолжить загрузку сайта, прерванную в предыдущий раз.
Most systems (at least my macbook) have system users defined, such as _www and using "users" for example will not list them. This command allows you to see who the 'virtual' users are on your system. Show Sample Output
Actually your func will find both files and directorys that contain ${1}. This one only find files. ..and to look only for dirs: finddir() { find . -type d -iname "*${*}*" ; }
A good way to understand what you've let yourself in for. Potential project metric could be the count:
svn log | grep -c "bodge\|fudge\|hack\|dirty"
many have aliases like: alias ...="cd ../../" alias ....="cd ../../../" and so furth. ..() mitigates to need for those aliases, see sample output for an example # .. -> go up 1 directory # .. 4 -> go up 4 directories ..() { local DIR='' declare -i NUM=0 if [[ ${1} =~ ^[1-9][0-9]*$ ]] then while (( ${NUM} < ${1:-1} )) do DIR="${DIR}../" NUM=$(( ${NUM} + 1 )) done else DIR=.. fi cd "${DIR}" } Show Sample Output
this will increase the volume by 2 decibels on the pcm channel. the argument to -c is for which sound card to use, the arg after set is the channel (PCM, Master, etc.) and what to set by. related commands: amixer -c 0 set PCM 2dB- decrease volume by 2 decibels amixer -c 0 set PCM toggle toggle mute/unmute this is for alsa systems for mac os (and maybe other UNIX systems) osascript -e 'set Volume *' where * is any number (can have decimal points) between 0 and 10
Well this can come handy , when you don't feel like playing with pid rather if you know the process name say "firefox",it would kill it.The script given below would kill the process with its name given as first parameter , though not robust enough to notify that process doesn't exist , well if you know what you are doing that's wouldn't be a problem.:) ---- killhim.sh ---- #!/bin/bash ps -u $USER |grep $1 | awk '{ print $1}'| xargs kill ----
* = where
This command does the following: - converts any sequence of multiple spaces/tabs to one space only - completely removes any space(s)/tab(s) at the end of each line (If spaces and tabs are mixed in a sequence i.e. [tab][tab][space][tab], you have to execute this command twice!) Show Sample Output
Will search recursively and output the searchResult.txt in the same folder you are located.
This doesn't work in bash, but in zsh you can typeset -T to bind a scalar variable to an array. $PATH and $path behave this way by default.
You can easily stop shutdowning process by CTRL+C
