A partir de hoje vou comentar neste blog alguns comandos para dar soluções a pequenos problemas que um utilizador ou administrador de sistemas Linux se pode deparar. A secção vai chamar-se QLC – Quick Linux Commands.

1º Quick Linux Commands: ps awwx

Se precisarem de mostrar a linha completa do comando a correr num sistema, podemos usar a flag ‘ww‘ do comando ‘ps‘

Exemplo:

[root@proxy07 root]# ps awx|grep java
28120 ?        S      0:23 /etc/iscan/AdminUI/jre/bin/java -Djava.library.path=/etc/iscan/lib/mt:/etc/iscan/lib -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djava.endorsed.dirs=/etc/iscan/AdminUI/tomcat/common/endorsed -classpath /etc/iscan/AdminUI/jre/lib/tools.jar:/etc/iscan/AdminUI/tomcat/bin/bootstrap.jar -Dcata



[root@proxy07 root]# ps awwx|grep java
28120 ?        S      0:23 /etc/iscan/AdminUI/jre/bin/java -Djava.library.path=/etc/iscan/lib/mt:/etc/iscan/lib -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djava.endorsed.dirs=/etc/iscan/AdminUI/tomcat/common/endorsed -classpath /etc/iscan/AdminUI/jre/lib/tools.jar:/etc/iscan/AdminUI/tomcat/bin/bootstrap.jar -Dcatalina.base=/etc/iscan/AdminUI/tomcat -Dcatalina.home=/etc/iscan/AdminUI/tomcat -Djava.io.tmpdir=/etc/iscan/AdminUI/tomcat/temp org.apache.catalina.startup.Bootstrap start

NAME

…
x               Lift the BSD-style “must have a tty” restriction, which is
imposed upon the set of all processes when some BSD-style
options are used or when the ps personality setting is

all processes owned by you (same EUID as ps), or to list all
processes when used together with the a option.
