top -c command in linux to filter processes listed based on processname
提问by
top -c
Top lists all the processes, there are good options to filter the processes by username by using the option -u but I am wondering if there is any easy way to filter the processes based on processname listed under COMMAND column of the top output.
Top 列出了所有进程，有一些很好的选项可以使用选项 -u 按用户名过滤进程，但我想知道是否有任何简单的方法可以根据顶部输出的 COMMAND 列下列出的进程名过滤进程。
For Example I would want like top -some option -substring of processname and top displays pids only having this substring in its command name
例如，我想要 top -some option -substring of processname 和 top 显示仅在其命令名称中包含此子字符串的pid

Using pgrep to get pid's of matching command lines:
使用 pgrep 获取匹配命令行的 pid：
top -c -p $(pgrep -d',' -f string_to_match_in_cmd_line)
top -pexpects a comma separated list of pids so we use -d','in pgrep. The -fflag in pgrep makes it match the command line instead of program name.
top-p需要一个逗号分隔的 pid 列表，所以我们-d','在 pgrep 中使用。-fpgrep 中的标志使其匹配命令行而不是程序名称。

what about this?
那这个呢？
top -c -p <PID>

@perreal's command works great! If you forget, try in two steps...
@perreal 的命令效果很好！如果您忘记了，请分两步尝试...
example: filter top to display only application called yakuake:
示例：过滤顶部以仅显示名为 yakuake 的应用程序：
$ pgrep yakuake
1755
$ top -p 1755
useful top interactive commands 'c' : toggle full path vs. command name 'k' : kill by PID 'F' : filter by... select with arrows... then press 's' to set the sort
有用的顶级交互式命令 'c' ：切换完整路径与命令名称 'k' ：按 PID 杀死 'F' ：过滤... 用箭头选择...然后按 's' 设置排序
the answer below is good too... I was looking for that today but couldn't find it. Thanks
下面的答案也很好......我今天正在寻找，但找不到。谢谢
回答by nos
It can be done interactively
它可以交互式地完成
After running top -c, hit oand write a filter on a column, e.g. to show rows where COMMAND column contains the string foo, write COMMAND=foo
运行后top -c，点击o并在列上写一个过滤器，例如显示 COMMAND 列包含字符串 foo 的行，写COMMAND=foo
If you just want some basic output this might be enough:
如果您只想要一些基本输出，这可能就足够了：
top -bc |grep name_of_process

After looking for so many answers on StackOverflow, I haven't seen an answer to fit my needs.
在 StackOverflow 上寻找了这么多答案后，我还没有看到满足我需求的答案。
That is, to make top command to keep refreshing with given keyword, and we don't have to CTRL+C / top again and again when new processes spawn.
也就是说，要使 top 命令以给定的关键字保持刷新，并且我们不必在新进程产生时一次又一次地 CTRL+C / top 。
Thus I make a new one...
所以我做了一个新的......
Here goes the no-restart-needed version.
这是不需要重启的版本。
__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; sleep 1; done;)
Modify the __keyword and it should works. (Ubuntu 2.6.38 tested)
修改 __keyword，它应该可以工作。（Ubuntu 2.6.38 测试）
2.14.2015 added: The system workload part is missing with the code above. For people who cares about the "load average" part:
2.14.2015 添加：系统工作负载部分与上述代码缺失。对于关心“平均负载”部分的人：
__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; uptime; sleep 1; done;)

I ended up using a shell script with the following code:
我最终使用了带有以下代码的 shell 脚本：

while [ 1 == 1 ]

clear
ps auxf |grep -ve "grep" |grep -E "MSG[^\ ]*" --color=auto
sleep 5
done

You can add filters to topwhile it is running, just press the okey and then type in a filter expression. For example, to monitor all java processes use the filter expression COMMAND=java. You can add multiple filters by pressing the key again, you can filter by user with the ukey, and you can clear all filters with the =key.
您可以在top运行时添加过滤器，只需按o键，然后输入过滤器表达式即可。例如，要监视所有 java 进程，请使用过滤器表达式COMMAND=java。再次按 键可以添加多个过滤器，可以用u键按用户过滤，用键可以清除所有过滤器=。

Most of the answers fail here, when process list exceeds 20 processes. That is top -poption limit.
For those with older top that does not support filtering with ooptions, here is a scriptable example to get full screen/console outuput (summary information is missing from this output).
当进程列表超过 20 个进程时，大多数答案都失败了。那是top -p期权限制。对于那些不支持使用o选项过滤的较旧顶部的用户，这里有一个可编写脚本的示例来获取全屏/控制台输出（此输出中缺少摘要信息）。
__keyword="YOUR_FILTER" ; ( FILL=""; for i in $( seq 1 $(stty size|cut -f1 -d" ")); do FILL=$'\n'$FILL; done ; while :; do HSIZE=$(( $(stty size|cut -f1 -d" ") - 1 )); (top -bcn1 | grep "$__keyword"; echo "$FILL" )|head -n$HSIZE; sleep 1;done )
Some explanations
一些解释
__keyword = your grep filter keyword
HSIZE=console height
FILL=new lines to fill the screen if list is shorter than console height
top -bcn1 = batch, full commandline, repeat once
