由 隐身守侯 提交于 2019-12-06 09:42:40
My .profile defines a function myps () { ps -aef|egrep "a|b"|egrep -v "c\-" } I'd like to execute it from my python script import subprocess subprocess.call("ssh user@box \"$(typeset -f); myps\"", shell=True) Getting an error back bash: -c: line 0: syntax error near unexpected token `;' bash: -c: line 0: `; myps' Escaping ; results in bash: ;: command not found The original command was not interpreting the ; before myps properly. Using sh -c fixes that, but... ( please see Charles Duffy comments below ). Using a combination of single/double quotes sometimes makes the syntax easier to read and

Could an existing fd always be duplicated both as input and output?

由 ＊爱你＆永不变心＊ 提交于 2019-12-06 08:23:59
问题 In bash, once a fd is in use (either as input or output): exec 7>AFile It seems that that fd number could be duplicated, both as input or output: true <&7; echo $? true >&7; echo $? The tests could be repeated for a variable as: fd=7 rco="$(true >&${fd} 2>/dev/null; echo $?)" rci="$(true <&${fd} 2>/dev/null; echo $?)" And both exit values joined in one word as: [[ "$rco$rci" = "11" ]] && echo "The fd number $fd is free" The question is: Under which conditions will the exit value of "$rco$rci"

问题 #!/bin/ksh ######################### for i in {1..30} ;do echo $i done output is: {1..30} What is wrong in my code? 回答1: {1..30} belongs to bash . Use this: for((i=1;i<=30;i++)); do echo $i done 回答2: Alternatively you can switch to a while construction: i=1 while (( i <= 30 )) do echo $i (( i+=1 )) done 回答3: for {set x 0} {$x<10} {incr x} { puts "x is $x" } 来源： https://stackoverflow.com/questions/9977485/ksh-scripting-for-loop
